Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: All of the above
Concept:

Protein classification is systematically based on composition, solubility, and products of hydrolysis.

Formula:

$$N/A$$

Solution:

  • Simple proteins: Yield only amino acids upon hydrolysis (e.g., albumin).
  • Compound (Conjugated) proteins: Contain a non-protein prosthetic group attached to the amino acid sequence (e.g., glycoproteins).
  • Derived proteins: Formed from simple or conjugated proteins by physical or chemical degradation (e.g., peptones).
  • Therefore, all three categories constitute the primary classification of proteins based on physico-chemical properties.


Why other options are incorrect:

Because simple, compound, and derived are all valid categories, limiting the answer to just A, B, or C would be incomplete.

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.
