    The answer is D. Proteins that are targeted for lysosomes have mannose-6-phosphate on their sugar chains. The mannose-6-phosphate is on an external site on the protein so that it can be recognized by the mannose-6-phosphate receptor on the lysosomal surface, and would also be easily accessible to an antibody directed against it.

    Acid hydrolases (choice A) are enzymes found inside the lysosomes.

    Coated pits (the cellular site for receptor-mediated endocytosis) contain clathrin (choice B).

    Production of glucose-6-phosphate (choice C) from glucose is the first step in the process of glycolysis.

    Sialic acid (choice E) is a terminal glycosylation product added to proteins (usually those destined for secretion) in the Golgi apparatus.

    Q 2. In order to study calcium fluxes in living cells, a researcher employs fluorescent calcium indicators and laser scanning confocal microscopy. In her experiments, she stimulates smooth muscle cells using a variety of pharmacological agents, then videotapes the calcium fluxes in the cell in real time using the confocal microscope. Which of the following drugs would most likely produce the strongest calcium signal in the smooth muscle cells?

    A. Clonidine

    B. Isoproterenol

    C. Phentolamine

    D. Phenylephrine

    E. Timolol

    Q 2.

    The answer is D. Two pieces of information are necessary to answer this question. First, you must know the drug classes represented by the answer choices. Second, you must know what second messengers are associated with these receptors. Phenylephrine is an α1 agonist; α1 receptors are coupled to Gq, which stimulates phospholipase C (PLC), leading to hydrolysis of phosphatidylinositol-4,5-bisphosphate (PIP2), a phospholipid in the plasma membrane. PIP2 is split into two second messengers: inositol-1,4,5-triphosphate (IP3) and diacylglycerol. IP3 diffuses through the cytoplasm to internal storage sites, where it triggers the release of calcium, thus providing the signal for this experiment. Diacylglycerol remains in the membrane and activates protein kinase C.

    Clonidine (choice A) is an α2 agonist. α2 receptors are coupled to Gi, which inhibits adenylate cyclase, leading to decreases in intracellular cAMP levels.

    Isoproterenol (choice B) is a nonselective β agonist. All β receptors are coupled to Gs, which stimulates adenylate cyclase, leading to elevated intracellular cAMP levels.

    Phentolamine (choice C) is a nonselective α antagonist. This drug would prevent the increase in calcium caused by stimulation of α1 receptors.

    Timolol (choice E) is a nonselective β antagonist. This drug would prevent β-induced increases in cAMP.

    Q 3. Liver cells in culture were kept at 0°C and treated with trypsin to digest the receptors on the cell surface. The temperature was then raised to 37°C and radioactive LDL was added to the culture media. Several hours later, the labeled LDL was found to be inside the cells. This specific process of LDL uptake is

    A. active transport

    B. facilitated diffusion

    C. phagocytosis

    D. pinocytosis

    E. receptor-mediated endocytosis
  6. mahak

    mahak Guest

    Q 3.

    The answer is E. Even though the surface LDL receptors were digested by the trypsin, the recycling of unoccupied receptors to the cell surface provides a continual supply of new receptors to bind the labeled LDL. The LDL-receptor complex is internalized by receptor-mediated endocytosis.

    A glycosylated integral membrane protein with 7 transmembrane segments?

    Q 4. Which of the following is an example of a glycosylated integral membrane protein with 7 transmembrane segments?

    A. Adenylate cyclase

    B. Beta-adrenergic receptor for epinephrine

    C. Cystic fibrosis transmembrane conductance regulator channel

    D. Glucose transporter

    E. Na+/K+ ATPase

    mahak Guest

    Q 4.


    The answer is B. This question requires that you recognize the family of receptors that interact with G proteins to initiate a signal transduction cascade. These receptors are all glycosylated integral membrane proteins that have 7 transmembrane segments. Beta-adrenergic receptors for epinephrine are an example.

    Adenylate cyclase (choice A) is an intracellular effector protein involved in signal transduction. It is not an integral membrane protein.

    The cystic fibrosis transmembrane conductance regulator channel (choice C) is a cyclic AMP activated chloride channel.

    Glucose transporters (choice D) are integral membrane proteins with 12 membrane-spanning domains.

    Na+/K+ ATPase (choice E) pumps sodium into and potassium out of the cell. It provides energy for active transport by hydrolyzing ATP.

    In a patient with a small-cell carcinoma of the lung

    Q 5. In a patient with a small-cell carcinoma of the lung that autonomously secretes vasopressin?
    A. Blood volume contraction
    B. Decreased plasma atrial natriuretic peptide
    C. Hypernatremia
    D. Inappropriately concentrated urine
    E. Increased thirst
  10. mahak

    mahak Guest

    Q 5.

    The answer is D. A tumor that ectopically secretes vasopressin can produce a disorder called the syndrome of inappropriate antidiuretic hormone (SIADH). A hallmark of this disorder is excessive renal retention of free water with resultant hypervolemia, not blood volume contraction (choice A), and dilutional hyponatremia, not hypernatremia (choice C). The volume expansion leads to increased (not decreased, choice B) secretion of atrial natriuretic peptide (ANP) by atrial myocytes. The increased ANP is one of the factors that causes the kidney to increase sodium excretion and produce an inappropriately concentrated urine. Urine is typically hypertonic to plasma in this disorder. The volume expansion also tends to suppress renin secretion, and the resultant decrease in serum aldosterone may also contribute to the increased renal sodium excretion. The dilutional hypotonicity would inhibit (not stimulate, choice E) hypothalamic thirst mechanisms.

    Microstructure of an integral membrane protein

    Q 6. A cell biologist wishes to examine the microstructure of an integral membrane protein. She solubilizes the protein by destabilizing its association with the membrane lipid bilayer. Which of the following techniques did she most likely employ?

    A. Alterations in pH

    B. Detachment of protein prenyl groups

    C. Dissociation of phospholipid polar head groups

    D. Increase in ionic strength

    E. Interruption of hydrophobic interactions
  12. mahak

    mahak Guest


    6. The answer is E. This question is asking you what forces are responsible for retaining integral membrane proteins within the lipid bilayer, i.e., hydrophobic interactions. Amphipathic agents such as detergents are used to solubilize integral membrane proteins; they do so by disrupting hydrophobic interactions between integral membrane proteins and other membrane constituents, such as phospholipids.

    Choices A, B, C, and D would destabilize the association of peripheral membrane proteins with the membrane lipid bilayer.

    Q 7. A 55-year-old patient presents with chronic cough. A chest x-ray film demonstrates a circular lesion near the apex of the lung. CT-guided biopsy of the lesion demonstrates a malignant tumor arising in an area of scarred lung. Which of the following type of cancer is most likely to be present?
    A. Adenocarcinoma
    B. Bronchioloalveolar carcinoma
    C. Large cell carcinoma
    D. Oat cell carcinoma
    E. Squamous cell carcinoma
  14. mahak

    mahak Guest

    7. The answer is A. Tumors that arise peripherally and can cause coin lesions include adenocarcinoma (choice A), bronchioloalveolar carcinoma (choice B), and large cell carcinoma (choice C). Of these, adenocarcinoma is the form specifically associated with lung scarring related to old granulomatous disease, old chronic obstructive lung disease, or other old damage to the lungs.
    Remember bronchioloalveolar carcinoma (choice B) as the one that is not associated with smoking.
    Large cell carcinoma (choice C) is an aggressive, undifferentiated form of lung cancer.
    Remember oat cell (small cell, choice D) carcinoma as the one that can commonly cause paraneoplastic syndromes such as SIADH and Cushing syndrome.
    You should associate squamous cell carcinoma of the lung (choice E) with hypercalcemia

    Q. 8 A medical student is studying a liver biopsy taken from a regenerating liver following a partial hepatectomy. The student sees a dividing cell in which the chromosomes are aligned on a plate. Which of the following best describes the character of the chromosomes in the plate?

    A. 23 chromosomes with 2N DNA total and with each chromosome having one chromatid

    B. 23 chromosomes with 4N DNA total and with each chromosome having two chromatids

    C. 46 chromosomes with 2N DNA total and with each chromosome having one chromatid

    D. 46 chromosomes with 4N DNA total and each chromosome having two chromatids

    E. 92 chromosomes with 2N DNA total and with each chromosome having two chromatids
  16. guest2011

    guest2011 Moderator

    8. Explanation:

    The answer is D. The cell division is mitotic rather than meiotic. The cell is in metaphase, as evidenced by alignment of chromosomes on the metaphase plate. Doubling of the DNA occurs much earlier, in prometaphase (late prophase), so the cell has "4N" DNA (double the normal 2N diploid DNA). The chromosomes at the metaphase plate consist of 2 chromatids each, but the total number of chromosomes is still the normal 46.

    23 chromosomes with 2N DNA (choice A) is wrong because stages with 23 chromosomes only occur in meiosis.

    23 chromosomes with 4N DNA (choice B) is wrong because stages with 23 chromosomes only occur in meiosis. Additionally, there is never a point in either meiosis or mitosis when 23 chromosomes contain 4N DNA.

    46 chromosomes with 2N DNA, each chromosome having one chromatid (choice C), is wrong because the chromosomes have two chromatids and the DNA is therefore doubled (producing 4N DNA total) in metaphase. The cell normally has 46 chromosomes with 2N DNA only after mitosis is complete.

    92 chromosomes (choice E) is wrong because in anaphase and telophase, at which points there are 92 chromosomes (in two cells which are not yet cleaved), there is a total of 4N DNA and each of the newly split chromosomes contains one chromatid.

    Choice (B) is the answer.

    Small cell lung carcinoma is an extremely aggressive neuroendocrine tumor that is associated with cigarette smoking. Neuroendocrine tumors commonly produce hormones. Small cell lung carcinoma is associated with both SIADH and ectopic ACTH production. SIADH results in hyponatremia and ectopic ACTH causes Cushing's syndrome. Small cell tumors are centrally located. Symptoms include constitutional symptoms such as fevers, fatigue, and unintended weight loss. Cough and hemoptysis may be present, along with hoarseness resulting from recurrent laryngeal nerve compression. Small cell carcinomas are characterized histologically by sheets of small, round, blue cells with very little cytoplasm.

    Q. 12 .Physical examination shows a blood pressure of 140/70 with no orthostasis, normal jugular venous pressure, and no edema. Serum chemistries are notable for sodium 120 mmol/L, K 4.2 mmol/L, bicarbonate 24 mmol/L, and uric acid 0.177 mmol/L (2 mg/dL). The most likely diagnosis is
    (A) hepatic cirrhosis
    (B) cerebral toxoplasmosis with SIADH
    (C) Addison's disease
    (D) significant gastrointestinal fluid loss
    (E) congestive heart failure
  24. guest2011

    guest2011 Moderator

    The answer is B.

    Hyponatremia can be broadly categorized as hypovolemic, euvolemic, or hypervolemic. Hepatic cirrhosis in this case is unlikely because of the absence of edema. Gastrointestinal fluid loss is unlikely because of normal blood pressure without orthostasis. Furthermore, depending on whether the fluid loss is upper (vomiting with resultant alkalosis) or lower (diarrhea with resultant acidosis), it often is accompanied by a disturbance in acid-base balance. Addison's disease is possible, although it often is associated with orthostasis, some degree of hypotension, and hyperkalemia (due to aldosterone deficiency). The uric acid can be very helpful in the differential diagnosis of hyponatremia. It is typically elevated in patients with congestive heart failure and renal failure, two other important causes of hyponatremia, and tends to be quite low in patients with SIADH.

    Paradoxical embolism is aassage of a clot likethrombus from a vein to an artery, When clots in veins break off..embolize they travel first to the right side of the heart and, normally, then to the lungs where they lodge, causing pulmonary embolism. On the other hand, when there is a hole in the wall between the two upper chambers of the heart (an atrial septal defect), a clot can cross from the right to the left side of the heart, then pass into the arteries as a paradoxical embolism.

    Q 18. A 70 kg male develops a tonic-clonic seizure. On admission to the hospital, his serum sodium is 120 mEq/Liter. He is euvolemic. Assuming a normal sodium concentration of 140 mEq/Liter, how much excess free water does he have?

    A.2 Liters

    B.3 Liters

    C.4 Liters

    D.5 Liters

    E.6 Liters

    F.7 Liters

    G.8 Liters
  35. guest2011

    guest2011 Moderator

    Choice (E) is the answer.

    The patient is severely hyponatremic, which means that he has more free water in relation to sodium. Excess free water can be calculated as follows:

    Excess free water (L) = TBW - [TBW x ([Na]pl / 140)]

    where TBW = total body water and [Na]pl = plasma sodium concentration. In males, total body water in liters is equal to 0.6 x weight in kg. In this example, total body water is equal to 42 Liters. 120 / 140 can be reduced to 6 / 7. (42 x 6/7) is equal to 36. 42 - 36 = 6 Liters. This patient has 6 Liters of excess free water that is resulting in hyponatremia. The most common cause of euvolemic hyponatremia in hospitalized patients is SIADH or syndrome of inappropriate antidiuretic hormone. Increased ADH levels result act on the renal collecting ducts to increase free water reabsorption. Excessive reabsorption of free water results in hyponatremia. Other causes of euvolemic hyponatremia include medications, stress, hypothyroidism, and glucocorticoid deficiency.
