, Q1. In a patient with chronic heart failure, which mechanism primarily contributes to
the transition from compensatory hypertrophy to decompensated failure?
A. Sustained activation of the -adrenergic receptor pathway leading to cardiomyocyte
apoptosis
B. Increased expression of SERCA2a enhancing calcium reuptake
C. Downregulation of the renin-angiotensin-aldosterone system
D. Enhanced nitric oxide bioavailability in the coronary microvasculature
Correct Answer: A. Sustained activation of the -adrenergic receptor pathway leading
to cardiomyocyte apoptosis
Rationale: Chronic sympathetic activation in heart failure leads to ²-receptor
desensitization and downregulation, but sustained catecholamine exposure also triggers
cardiomyocyte apoptosis and fibrosis, contributing to decompensation. SERCA2a is
typically downregulated, RAAS is upregulated, and nitric oxide is reduced, not enhanced.
Why Wrong:
B - SERCA2a is downregulated in heart failure, impairing calcium reuptake, not
increased.
C - RAAS is activated, not downregulated, in chronic heart failure.
D - Nitric oxide bioavailability is reduced, contributing to endothelial dysfunction, not
enhanced.

Q2. Which of the following best explains the development of insulin resistance in
obesity?
A. Excess free fatty acids activate protein kinase C, impairing insulin receptor
substrate-1 signaling
B. Increased adiponectin levels enhance insulin sensitivity
C. Upregulation of GLUT4 transporters on adipocytes
D. Reduced inflammatory cytokine secretion from adipose tissue
Correct Answer: A. Excess free fatty acids activate protein kinase C, impairing
insulin receptor substrate-1 signaling
Rationale: Obesity leads to elevated free fatty acids that activate PKC-¸, which
serine-phosphorylates IRS-1, reducing insulin signaling. Adiponectin is decreased, GLUT4
is downregulated, and inflammatory cytokines are increased, all promoting resistance.
Why Wrong:
B - Adiponectin levels are decreased in obesity, not increased.
C - GLUT4 expression is reduced, not upregulated, in insulin resistance.
D - Adipose tissue secretes more pro-inflammatory cytokines, not fewer.
