Propolis Cognitive Error Autopsy
Official Correct Choice:
Option C: B-Lymphocytes
Concept: Cellular origin of antibodies.
Solution: B-lymphocytes possess membrane-bound B-cell receptors (BCRs). Upon antigen stimulation, they undergo expansion and differentiate into antibody-secreting plasma cells.
Why other options are incorrect:
Solution: B-lymphocytes possess membrane-bound B-cell receptors (BCRs). Upon antigen stimulation, they undergo expansion and differentiate into antibody-secreting plasma cells.
Why other options are incorrect:
- Option A: Neutrophils act via phagocytosis and degranulation.
- Option B: Monocytes differentiate into phagocytic tissue macrophages.
- Option D: T-lymphocytes mediate cell-mediated responses or release cytokines, but do not synthesize immunoglobulins.
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.
