Enzymes Known as Lyases Participate in ________ Reactions

Question

Enzymes known as lyases participate in ________ reactions.
A) anabolic
B) catabolic
C) both anabolic and catabolic
D) neither anabolic nor catabolic
E) oxidation-reduction

Accepted Answer

Lyases participate in catabolic reactions, which involve the breakdown of larger molecules into smaller ones. They catalyze the removal of groups from substrates, leading to the formation of a double bond, and can also add functional groups to double bonds. This can be seen in reactions such as the conversion of glucose-6-phosphate to pyruvate in glycolysis, which is catalyzed by the enzyme aldolase (a type of lyase).
