Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Neurotransmitters
Concept:

Action potentials cannot jump physical gaps; they require a chemical intermediary.

Solution:

  • Neurotransmitters are the packaged molecules stored in presynaptic vesicles that diffuse across the synaptic cleft to convey the neural message to the receptors of the adjacent post-synaptic neuron.


Why other options are incorrect:

  • Hormones: Transported via blood over long distances.


  • Enzymes: Proteins that speed up reactions (e.g., Acetylcholinesterase breaks down the message, rather than conveying it).

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.
