Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Peptide hormone
Concept: Chemical structure of hormones.

Solution: Vasopressin is a nonapeptide (a peptide hormone consisting of a 9-amino-acid chain) synthesized in the hypothalamus.

Why other options are incorrect:
  • Option A (Steroid): Lipid-soluble cholesterol derivatives (e.g., aldosterone, cortisol, estrogen).

  • Option B (Catecholamine): Amino acid derivatives (e.g., epinephrine, norepinephrine).

  • Option D (Glycoprotein): Complex protein hormones with carbohydrate side chains (e.g., TSH, FSH, LH).

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.
