Final answer:
An isomerase is the type of enzyme in glycolysis responsible for catalyzing the conversion between aldoses and ketoses, such as the conversion of glucose-6-phosphate into fructose-6-phosphate.
Step-by-step explanation:
The Type of Enzyme in Glycolysis That Converts an Aldose to a Ketose
The type of enzyme found in glycolysis that can catalyze the conversion of an aldose to a ketose, or vice versa, is a) Isomerase. During glycolysis, glucose-6-phosphate isomerase, a specific type of isomerase, converts glucose-6-phosphate (an aldose) into fructose-6-phosphate (a ketose). This allows the molecule to be eventually split into two three-carbon molecules. An isomerase is an enzyme that catalyzes the conversion of a molecule into one of its isomers, in this case, changing an aldose to a ketose or the reverse.
Further in the glycolysis pathway, the enzyme aldolase breaks down fructose-1,6-bisphosphate into two three-carbon isomers, showcasing another action of enzymes in this metabolic process. Moreover, triosephosphate isomerase also demonstrates this activity by converting dihydroxyacetone phosphate (DHAP) into glyceraldehyde-3-phosphate, making it a vital enzyme for the continuation of glycolysis.
