PMDC Verified Question 17 of 86
During the conduction of nerve impulse, hyperpolarization would not occur if:
A
Sodium Potassium pump stopped working
B
Sodium gates did not close in time
C
Potassium gates were not so lousy
D
Calcium gets open instantly

Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Potassium gates were not so lousy
Concept: Voltage-gated potassium channel kinetics.

Solution: Hyperpolarization occurs because voltage-gated \(K^+\) channels close slowly, allowing excess positive \(K^+\) to leak out. If \(K^+\) channels closed promptly upon reaching resting potential, hyperpolarization would not occur.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
