APFIVE Enzyme Conservation During Catalysis
Which of the following pieces of evidence best supports the conclusion that enzymes are not consumed during the reactions they catalyze?
A
Data indicating that the enzyme concentration significantly decreases during the reaction.
B
Evidence that the enzyme undergoes permanent structural alteration during catalysis.
C
Measurements showing that enzyme molecules are used up and must be continuously resynthesized during the reaction.
D
Observations showing that enzyme molecules remain unchanged in both structure and quantity before and after the reaction.
