Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Hydrolysis
Concept:

Biological digestion is entirely reliant on the chemical cleavage of macromolecules using water.

Solution:

  • When we consume a protein, our digestive enzymes (like pepsin and trypsin) must break the tough, covalent peptide bonds linking the amino acid chain.


  • This is accomplished strictly through a Hydrolysis reaction, wherein a single water molecule is forced into the peptide bond, splitting it apart to release individual, absorbable amino acids.


Why other options are incorrect:

  • Condensation: The exact opposite process; removes water to build the protein up.


  • Glycolysis: The metabolic breakdown of glucose for energy, entirely unrelated to protein digestion.


  • Fixation: Converting inorganic gas (like \(CO_2\) or \(N_2\)) into organic forms (photosynthesis).

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.
