Living things use enzymes in the chemical reactions of metabolism. When 2 points food is digested, it is metabolized to release energy. Which statement
best describes the role of an enzyme in this process?

Because enzymes are proteins, they only react with other protein molecules, resulting
in the production of glucose.

The active site of an enzyme attached to a substrate prevents the chemical
reactions involved in metabolism from happening too quickly

The active site of the enzyme binds to a substrate on a food molecule and the enzyme
changes shape slightly, causing a chemical reaction to happen.
