Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Concave, maturing face
Concept: The Golgi apparatus has a distinct polarity, with a receiving end and a shipping end.

Solution: The Golgi has a forming face (cis, convex) where vesicles from the ER arrive and fuse. After processing, the secretory vesicles bud off and break away from the trans face, which is concave and known as the maturing face.

Distractor Autopsy: The forming face is convex (receives), while the maturing face is concave (dispatches). Therefore, combining "forming" with "concave" or "maturing" with "convex" is structurally inaccurate.

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.
