Question

Enzymes - What do they do? Do they cause or facilitate reactions? Are they consumed by the reaction? Can they be used over and over again?

a) Enzymes initiate chemical reactions
b) Enzymes facilitate reactions by being consumed
c) Enzymes are not involved in biological reactions
d) Enzymes facilitate reactions and can be used repeatedly

Answer 1

Enzymes are biological catalysts that facilitate chemical reactions without being consumed by the reaction and can be used repeatedly.

Step-by-step explanation:

Enzymes are biological catalysts that facilitate chemical reactions without being consumed by the reaction. They can be used over and over again because they are not used up in the reactions. Enzymes are highly specific for particular chemical reactions and generally catalyze only one or a few types of reactions.
