Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Lipoprotein
Concept:

Viral envelopes are structurally derived from the host cell but modified by the virus.

Solution:

  • When HIV buds out of a host cell, it wraps itself in a section of the host's plasma membrane.
  • This biological membrane is primarily composed of lipids with embedded viral proteins, classifying it biochemically as a lipoprotein envelope.


Why other options are incorrect:

  • Glycoprotein: Refers specifically to the spikes (gp120/gp41) sticking out of the envelope, not the continuous membrane layer itself.

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.
