Question

multiple choice question
what happens when salivary amylase, which works best at a ph of 7, is exposed to acids of the stomach?
o it speeds up reactions.
o it changes its substate.
o it becomes inactivated.

Explanation:

Enzymes like salivary amylase have an optimal pH for activity. The stomach has a very low (acidic) pH which is far from the optimal pH of 7 for salivary amylase. Extreme pH can denature enzymes, causing them to lose their 3 - D structure and become inactive.

Answer:

It becomes inactivated.
