Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Peptide hormone
Concept:

Vasopressin, also known as Antidiuretic Hormone (ADH), regulates water reabsorption in the kidneys.

Solution:

  • Vasopressin is synthesized in the hypothalamus and consists of a short chain of exactly 9 amino acids.


  • Because it is composed of a short amino acid chain, it is structurally classified as a peptide hormone.


Why other options are incorrect:

It is not a steroid (which is lipid-based), not a catecholamine (like adrenaline), and not a glycoprotein (which would have attached carbohydrate chains like FSH).

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.
