Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Graffian follicle – Progesterone
Concept:

Hormone production shifts entirely based on the pre- vs. post-ovulatory state of the follicle.

Solution:

  • Let's analyze the pairs:


  • A. Graafian follicle – Progesterone: This is MISMATCHED. The Graafian (pre-ovulatory) follicle primarily secretes estrogen. It only begins secreting progesterone after it ruptures and transforms into the corpus luteum.


  • B. ICSH stimulates interstitial cells to produce testosterone. (Correct pair)


  • C. Estrogen provides negative feedback to inhibit FSH. (Correct pair)


  • D. LH surge triggers ovulation. (Correct pair)


Why other options are incorrect:

Because options B, C, and D represent factual, core biological relationships, option A is the only biologically incorrect association.

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.
