    Correct

    • The transporter responsible for most glucose absorption in the lumen of the small intestine is called?

      Your Answer: SGLT 1

      Explanation:

      GLUT = Glucose transporter. GLUT are a family of proteins of different types. GLUT 1 is mainly expressed in erythrocytes, whereas GLUT 2 is mainly expressed by, liver cells and renal tubular cells. GLUT 5 is a sucrose transporter in enterocytes. SGLT- Sodium-dependent glucose cotransporter or sodium-glucose linked transporter are a family of proteins of different types. SGLT1 transporter is found in the intestinal mucosa of the small intestine and SGLT2 in the proximal tubule of the nephron.

    Incorrect

    • Tumour necrosis factor is a cytokine. What is its major function?

      Your Answer: Chemotaxis of t cells

      Correct Answer: Promotion of inflammation

      Explanation:

      Tumour necrosis factor (TNF) is a cytokine that has a wide variety of functions. It can cause cytolysis of certain tumour cell lines; it is involved in the induction of cachexia; it is a potent pyrogen, causing fever by direct action or by stimulation of interleukin-1 secretion; it can stimulate cell proliferation and induce cell differentiation under certain conditions.

    Correct

    • In a 30 year old male with hypertrophic obstructive cardiomyopathy (HOCM), which of the following is not associated with increased risk of sudden death?

      Your Answer: Age

      Explanation:

      Hypertrophic cardiomyopathy (HCM) is a disease in which a portion of the myocardium (heart muscle) is enlarged without any obvious cause, creating functional impairment of the heart. It is the leading cause of sudden death in young athletes. The major risk factors for sudden death (SD) are recent unexplained syncope unlikely to be neurocardiogenic; HCM-related SD in first-degree or other close relatives; repetitive and/or prolonged nonsustained ventricular tachycardia (NSVT) episodes on Holter or extended ambulatory monitoring; massive left ventricular hypertrophy (LVH) (wall thickness ≥30 mm); extensive/diffuse late gadolinium enhancement (LGE); end-stage heart failure usually with systolic dysfunction; and thin-walled akinetic LV apical aneurysm with regional scarring.

    Correct

    • Which one of the following diuretics is associated with metabolic acidosis?

      Your Answer: Acetazolamide

      Explanation:

      Acetazolamide is in the diuretic and carbonic anhydrase inhibitor families of medication. It works by decreasing the amount of hydrogen ions and bicarbonate in the body and can thus cause metabolic acidosis and electrolyte changes (hypokalaemia, hyponatremia).

    Correct

    • Which vitamin is found in NAD and NADP?

      Your Answer: Vitamin B3

      Explanation:

      In organisms, NAD can be synthesized from simple building-blocks (de novo) from the amino acids tryptophan or aspartic acid. In an alternative fashion, more complex components of the coenzymes are taken up from food as the vitamin called niacin (vitamin B3)

    Incorrect

    • Which part of the neuron has the highest concentration of sodium channels per square millimetre of the cell membrane?

      Your Answer: Cell body 50-75

      Correct Answer: Nodes of Ranvier

      Explanation:

      The nodes of Ranvier contain Na+/K+ ATPases, Na+/Ca2+ exchangers and a high density of Na+ channels. The estimated concentration of sodium channels in the node is of ∼1500/μm2.

    Correct

    • Which immunological cells are predominant in the lymph node (almost 98 % residence)?

      Your Answer: Lymphocytes

      Explanation:

      Lymph nodes are a lymphoid organ mostly consisting of lymphocytes: B cells in the cortex from where they mature and proliferate and T cells in the paracortex. The medulla is also composed of lymphocytes and macrophages.

    • Coronary flow is reduced during

      Your Answer: Tachycardia

      Explanation:

      Maximum amount of blood flow in the coronary arteries occur during diastole. When the heart rate increases which is also called tachycardia the duration of diastole decreases. Hence the amount of blood flow to the cardiac muscle also decreases.

    Incorrect

    • A 42 year old female presents with a funny bone sensation in her right elbow that is accompanied by numbness and tingling in the 4th and 5th digits. The symptoms are aggravated when the elbow is bent for a prolonged period. Which of the following explains the most likely diagnosis?

      Your Answer: Medial epicondylitis

      Correct Answer: Cubital tunnel syndrome

      Explanation:

      Cubital Tunnel Syndrome is a condition that involves pressure or stretching of the ulnar nerve (also known as the “funny bone” nerve), which can cause numbness or tingling in the 4th and 5th digit, pain in the forearm, and/or weakness in the hand. Epicondylitis of the elbow is a condition associated with repetitive forearm and elbow activities. Both lateral epicondylitis (commonly known as tennis elbow) and medial epicondylitis (commonly known as golfer’s elbow) are characterized by elbow pain during or following elbow flexion and extension. Radial tunnel syndrome is a set of symptoms that include fatigue or a dull, aching pain at the top of the forearm with use. Although less common, symptoms can also occur at the back of the hand or wrist.

    Incorrect

    • Cyclic AMP activates the following enzyme

      Your Answer: Adenylyl cyclase

      Correct Answer: Protein Kinase A

      Explanation:

      Cyclic AMP works by activating protein kinase A (PKA, or cAMP-dependent protein kinase). Protein kinase A can also phosphorylate specific proteins that bind to promoter regions of DNA, causing increases in transcription.
