Digestion of protein within the stomach begins with the enzyme

Question

Select one:
O a. pepsinogen.
O b. trypsinogen.
O c. pepsin.
• d. protease.

Answer 1

The digestion of protein within the stomach begins with the enzyme c. pepsin.

Pepsin is activated from its inactive form, pepsinogen, in the acidic environment of the stomach. So while pepsinogen is involved in the process, it is the action of pepsin that actually begins the digestion of proteins.
