, Q1. In a cell with a non-functioning Na+/K+-ATPase due to metabolic poisoning,
which of the following immediate changes is most likely to occur?
A. Increased intracellular Ca2+ due to reversal of the Na+/Ca2+ exchanger
B. Decreased intracellular Na+ due to decreased ATP hydrolysis
C. Hyperpolarization of the resting membrane potential
D. Increased intracellular K+ due to reduced efflux through leak channels
Correct Answer: A. Increased intracellular Ca2+ due to reversal of the Na+/Ca2+
exchanger
Rationale: Na+/K+-ATPase failure raises intracellular Na+, reversing the Na+/Ca2+
exchanger to import Ca2+. This leads to cytosolic Ca2+ overload and cell injury. The
other options are incorrect because Na+ accumulates, membrane potential depolarizes,
and K+ is lost.
Why Wrong:
B - Na+ would increase, not decrease, without active extrusion.
C - Loss of the electrogenic pump and K+ gradient causes depolarization, not
hyperpolarization.
D - K+ leaks out down its gradient, and without the pump it cannot be replenished, so
intracellular K+ falls.

Q2. A researcher is studying a novel cytokine that induces the expression of
acute-phase proteins in hepatocytes. Which intracellular signaling pathway is most
directly activated by this cytokine to produce this effect?
A. JAK-STAT pathway
B. MAP kinase pathway
C. Phospholipase C pathway
D. NF-B pathway
Correct Answer: A. JAK-STAT pathway
Rationale: IL-6, a key acute-phase cytokine, signals through the JAK-STAT pathway to
induce acute-phase protein synthesis in the liver. The other pathways mediate different
cytokine responses: MAP kinase for growth, PLC for calcium signaling, and NF-B for
inflammatory gene transcription.
Why Wrong:
B - MAP kinase is more associated with mitogenic and stress responses, not directly
with acute-phase protein induction.
C - PLC generates IP3 and DAG, which are not the primary mediators of acute-phase
protein gene transcription.
D - NF-B is involved in inflammatory cytokines, but IL-6's classic acute-phase
