Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Chemoreceptors
Concept:

Gustation (taste) is fundamentally a chemical sense.

Solution:

  • Taste buds contain gustatory cells that bind to specific food molecules (tastants) dissolved in saliva. Because they detect chemical substances, they are classified as chemoreceptors.


Why other options are incorrect:

  • Thermoreceptors / Pressure receptors: Present on the tongue for temperature and texture, but they are not the taste buds themselves.


  • Photoreceptors: Found only in the retina of the eye.

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.
