Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: L-asparaginase
Concept:

Enzyme therapy leverages the metabolic weaknesses of specific cancer cells.

Formula:

$$N/A$$

Solution:

  • Childhood acute lymphoblastic leukemia (blood cancer) cells require circulating L-asparagine for survival because they lack the enzyme to synthesize it themselves.
  • By injecting L-asparaginase into the patient, the circulating L-asparagine is hydrolyzed into aspartic acid and ammonia.
  • Starved of this essential amino acid, the cancer cells undergo apoptosis (programmed cell death).


Why other options are incorrect:

Thrombin is used locally to stop bleeding. LDH-1 levels are diagnostic markers for heart attacks. Zymase is a yeast enzyme used in ethanol fermentation.

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.
