The reaction catalyzed by triose phosphate isomerase is most similar in mechanism to which of the following glycolytic enzymes?

Question

Quizplus · Accepted Answer

Both triose phosphate isomerase and glucose-6-phosphate isomerase catalyze isomerization reactions, which involve the conversion of one isomer to another without a change in the number of carbon atoms. In particular, triose phosphate isomerase catalyzes the conversion of glyceraldehyde-3-phosphate to dihydroxyacetone phosphate, while glucose-6-phosphate isomerase catalyzes the conversion of glucose-6-phosphate to fructose-6-phosphate. The other enzymes listed (fructose-1,6-bisphosphate aldolase, phosphoglycerate mutase, enolase, and pyruvate kinase) catalyze more complex reactions involving bond cleavage or formation.
