which of the following best describes the relationship between the shape of enzymes and the reactions they catalyze?
enzymes change shape after they catalyze a reaction and become waste products
the shape of an enzyme depends on the reaction that it needs to catalyze
the shape of an enzyme determines which reaction it can catalyze
enzymes with more active sites can catalyze several reactions at once
which of the following best describes what happens to an enzyme after it catalyzes a chemical reaction?
it becomes chemically bonded to the products of the reaction
its mass decreases since part of the molecule is used up
its shape changes, giving it different chemical and physical properties
it is unchanged and can be used again for the same chemical reaction

Explanation:

Enzymes are biological catalysts. They are not consumed in the chemical reactions they catalyze, meaning their chemical nature and quantity remain the same after the reaction, allowing them to be used again for the same chemical reaction.

Answer:

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