What happens when pepsin enters the small intestine?

A. It is digested due to the high pH.
B. It activates HCl.
C. It inhibits pepsinogen synthesis.
D. It denatures protein structures.
E. It cleaves proteins into smaller peptides and some free amino acids.



Answer :

Final answer:

When pepsin enters the small intestine, it cleaves proteins into smaller peptides and some free amino acids, aiding in protein digestion.


Explanation:

When pepsin enters the small intestine, it continues its function by cleaving proteins into smaller peptides and some free amino acids. This enzymatic action aids in further digesting proteins that were partially broken down in the stomach. The small intestine releases digestive enzymes and hormones to facilitate this process.
