Quizplus · Accepted Answer

Pepsin is an enzyme that works in the stomach, which is an acidic environment due to the presence of hydrochloric acid. Pepsin is most active at a pH of 1.5 to 2, which is highly acidic. Amylase, trypsin, and sucrose are all enzymes that work in a neutral pH environment, while gastrin is a hormone, not an enzyme. Therefore, pepsin is the best choice for an enzyme that has high activity in an acidic environment.
