Enzymes

Enzymes are used up during metabolic reactions.

Enzymes are specific to a particular shape of substrate. (correct)

Enzymes do not lower the activation energy required for a reaction.

Enzymes are made up of nucleic acids.

Anabolic reactions break down molecules to their constituents.

Enzymes are only used in catabolic reactions.

Catabolic reactions release energy used in anabolic reactions. (correct)

Catabolic reactions build molecules from smaller ones.

Enzymes are not involved in metabolic reactions.

Enzymes bind tightly to the substrate to lower the transition state. (correct)

Enzymes have a lower affinity for the transition state than the substrate.

Enzymes increase the activation energy required for a reaction.
