Question

multiple - choice question
why do enzymes that work in the stomach have an optimal ph of 2?
the stomach is a basic environment
the stomach is an acidic environment
they are really tough

Explanation:

The stomach contains hydrochloric acid, creating an acidic environment (pH around 1.5 - 3.5). Enzymes in the stomach (like pepsin) have an optimal pH of 2 to function best in this acidic condition. The first option is incorrect as the stomach is not basic, and the third option is not a scientific reason related to pH adaptation.

Answer:

B. the stomach is an acidic environment
