Question

An enzyme with high activity in an acidic environment is
A)amylase.
B)pepsin.
C)gastrin.
D)trypsin.
E)sucrose.

Accepted Answer

Pepsin is a digestive enzyme that is produced in the stomach and has optimal activity in an acidic environment (pH 1.5-2.5). It functions to break down proteins into smaller peptides. Amylase, gastrin, trypsin, and sucrose are not enzymes that are particularly active in an acidic environment.
