Question

why does changing the pH of a solution affect the ability of an enzyme to catalyze a chemical reaction

Answer 1

the change in ph alters the ionic bonds within the enzymes tertiary shape
that causes its shape to alter and so its less efficient
altering the ph away from the extremes closer to its optimum PH will alter it back usually
hope that helps

Answer 2

The answer is: Most enzymes are very sensitive to changes in pH.

Step-by-step explanation:

Most enzymes are very sensitive to pH changes. Deviations of a few tenths above or below the optimum pH can drastically affect your activity. It also affects the form and therefore the reaction rate, each enzyme has an optimal pH.

The answer is: Most enzymes are very sensitive to changes in pH.
