Concept:Classification of proteins depends heavily on their products of complete hydrolysis.
Formula:$$ \text{Simple Protein} \xrightarrow{\text{Hydrolysis}} \text{Only Amino Acids} $$
Solution:- The question states that globulins yield only amino acids (or their direct derivatives) upon hydrolysis and do not yield any non-protein prosthetic groups.
- By definition, macromolecules that yield only amino acids upon hydrolysis are classified as simple proteins.
Why other options are incorrect:Compound and conjugated proteins are synonymous; both yield non-protein prosthetic groups (like lipids or carbohydrates) alongside amino acids. Derived proteins are denatured or partially broken-down proteins, whereas globulins are native functional proteins.
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.
