In an experiment to study the effect of proteases on proteins, what is the most likely effect of a major change in ph? a) increased rate of product formation b) a change in the substrate concentration c) the formation of new active sites of the enzyme d) a change in shape of the active sites of the enzyme

The correct answer is-

D) a change in shape of the active sites of the enzyme.

Enzymes are primarily protein molecules that drive various chemical reactions ( by increasing the rate of reaction) within the body of living organisms.

Protease is a protein digesting enzyme that works on specific pH ( such as pepsin works on pH 2 within stomach, which is highly acidic) .

Shape of an enzyme determine its function as they have active sites ( which have unique shapes) that fit in the substrate and carry out the chemical reactions.

A major change in pH can alter the shape of the active sites of the enzyme, making it inactive.

Thus, option D) is the right answer.
