Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Pinocytosis
Concept: Bulk transport across the membrane occurs via vesicle formation, categorized by the physical state of the ingested material.

Solution: Pinocytosis (cell drinking) is the specific form of endocytosis involving the ingestion of liquid materials or extracellular fluid by the budding of small vesicles from the cell membrane.

Distractor Autopsy:
  • Phagocytosis: Intake of large solid particles (cell eating).
  • Endocytosis: A general term that includes both pinocytosis and phagocytosis. Pinocytosis is the more precise answer for liquids.

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.
