Question

which of the following best describes what happens to an enzyme after it catalyzes a chemical reaction? o it becomes chemically bonded to the products of the reaction. o its mass decreases since part of the molecule is used up. o its shape changes, giving it different chemical and physical properties. o it is unchanged and can be used again for the same chemical reaction.

Explanation:

Enzymes are biological catalysts. They speed - up chemical reactions without being consumed in the process. After catalyzing a reaction, their chemical and physical properties remain the same and they can be used again for the same reaction.

Answer:

It is unchanged and can be used again for the same chemical reaction.
