Which Reaction in Glycolysis is a Ketose to Aldose Isomerization

Question

Which reaction in glycolysis is a ketose to aldose isomerization?
A) hexokinase
B) phosphoglycerate mutase
C) enolase
D) aldolase
E) triose phosphate isomerase

Accepted Answer

The only reaction in glycolysis that involves an isomerization of a ketose to an aldose is the conversion of dihydroxyacetone phosphate (DHAP) to glyceraldehyde 3-phosphate (G3P) by triose phosphate isomerase.
