Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Large amount of hemoglobin
Concept:

Cellular contents of skeletal muscle.

Formula:

N/A (Conceptual)

Solution:

  • Skeletal muscle fibers are highly metabolically active syncytia. They naturally contain multiple nuclei, dense arrays of mitochondria (for ATP production), and myoglobin, a local oxygen-storing protein.


  • Hemoglobin, however, is strictly confined within Red Blood Cells circulating in the vascular system. It is not found inside the actual cytoplasm of skeletal muscle cells.


Why other options are incorrect:

Options A, B, and C describe structures specifically adapted to and found within human skeletal muscle tissue.

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.
