What do we know about the consumption of an enzyme during a metabolic reaction in the body?

Question

A.
The enzyme becomes part of the reactants.
B.
The enzyme becomes part of the products.
C.
The enzyme becomes part of the activated complex.
D.
The enzyme is not consumed.
E.
The consumption depends on the enzyme.

Answer 1

The correct answer is D. The enzyme is not consumed.

In metabolic reactions, enzymes act as catalysts, speeding up the reaction without being consumed or permanently changed in the process. They facilitate the conversion of substrates into products, but they are available to participate in many reaction cycles. Thus, they remain unchanged and can be reused multiple times.
