Final answer:

Aldolase catalyzes the breakdown of fructose-1, 6 bisphosphate into dihydroxyacetone phosphate and glyceraldehyde-3-phosphate during glycolysis, so the correct answer is E) B and C.

Step-by-step explanation:

During glycolysis, the enzyme aldolase catalyzes the breakdown of fructose-1, 6 bisphosphate to produce two products: dihydroxyacetone phosphate (DHAP) and glyceraldehyde-3-phosphate (G3P). This particular reaction of glycolysis does not produce phosphoenolpyruvate or fructose-6-phosphate. Thus, the correct answer to the student's question is D) A and B. However, since aldolase does not produce phosphoenolpyruvate directly, the true answer is E) B and C, representing dihydroxyacetone phosphate and glyceraldehyde-3-phosphate respectively, which are the actual products of the action of aldolase on fructose-1,6-bisphosphate.
