Problem: Which of the following enzymes catalyzes an aldose to ketose isomerization?A. Phosphoglycerate mutaseB. AldolaseC. Phosphohexose isomeraseD. Glyceraldehyde-3-phosphate dehydrogenaseE. Enolase

FREE Expert Solution

The enzymes given in the problem are used in several reactions in glycolysis. Aldolase, for example, is an enzyme that is involved in the hydrolysis of fructose 1,6-bisphosphate into dihydroxyacetone phosphate and glyceraldehyde-3-phosphate. Thus, it is not an isomerase (i.e. does not catalyze isomerization).
