Pepsin, a common enzyme found in the stomach, is most active at ph values between 0.5 and 2.5. it works slowly between ph values of 2.6 and 3.4. beyond a ph of about 3.5, it becomes completely inactive. why does this happen?
a. the change in ph affects the shape and function of the enzyme. it can only function properly in its optimal ph range.
b. the enzyme inactivates because it melts into a liquid when it is not at the right ph.
c. because a ph of 3.5 is an acid and eats away at the enzyme.
d. ph changes also affect temperature, and that affects the reaction.
