A decrease in pH may disrupt the functioning of an enzyme because:
A)the enzyme must help out the bicarbonate buffer system
B)the active site becomes clogged with excess water
C)the substrate fits into the active site but cannot get out
D)excess hydrogen ions may block the active site

Question

Quizplus · Accepted Answer

Excess hydrogen ions may block the active site of the enzyme, preventing the substrate from binding and disrupting the enzyme's function. This is known as denaturation, where the enzyme loses its shape and ability to catalyze reactions.
