Question

Which of the following is NOT true regarding enzymes?
a.Enzymes are composed of amino acids.
b.Enzymes have unique 3-dimensional shapes.
c.The substrate binds to the enzyme at the active site.
d.Enzymes are used up in the reaction.

Answer 1

Answer:

The answer is d.Enzymes are used up in the reaction.

Explanation:

Enzymes are never used in the reactions. As their function is to be a catalyst, therefore, they are not involved in any chemical reaction and they don't alter their composition. They do change, sometimes, their shape, in order to help properly with the catalysis, but that doesn't involve any other involvement of them.
