Differentiate between HCL and pepsin.

Answer»

Hydrochloric acid creates an acidic environment, which allows pepsinogen to unfold and cleave itself in anautocatalytic FASHION, thereby generatingpepsin (the active FORM). Pepsin cleaves the 44 amino acids from pepsinogen to create more pepsin..Pepsin is a STOMACH enzyme that serves to digest proteins found in INGESTED food. ... Parietal cells within the stomach lining secrete hydrochloric acid that lowers the pH of the stomach. A low pH (1.5 to 2) activates pepsin.
