Heating inactivates enzymes by
A) breaking the covalent bonds that hold the molecule together.
B) removing phosphate groups from the enzyme.
C) causing enzyme molecules to stick together.
D) changing the enzyme's three-dimensional shape.

Question

Quizplus · Accepted Answer

Heating can cause changes in temperature and/or pH, which can alter the conformation of the protein structure of the enzyme, leading to a loss of function. This is because the specific three-dimensional shape of an enzyme is crucial for its catalytic activity.
