Question

In glycolysis, the product(s) of the enzyme aldolase is (are)

A) beta-hydroxy carbonate.
B) dihydroxyacetone phosphate.
C) glyceraldehyde-3-phosphate.
D) choices A and B only
E) choices B and C only

Answer 1

In glycolysis, aldolase enzyme breaks down fructose-1,6-bisphosphate into dihydroxyacetone phosphate and glyceraldehyde-3-phosphate. The correct products of aldolase are E) choices B and C only.

Step-by-step explanation:

In glycolysis, the enzyme aldolase is responsible for a critical reaction that cleaves fructose-1,6-bisphosphate into two different three-carbon molecules. The products of this enzymatic reaction are dihydroxyacetone phosphate (DHAP) and glyceraldehyde-3-phosphate (G3P).

Following this cleavage, another enzyme, triosephosphate isomerase, can convert DHAP into glyceraldehyde-3-phosphate, leading to a net production of two glyceraldehyde-3-phosphate molecules from one molecule of glucose by the end of the first phase of glycolysis.

Given this information, the correct option for the products of the enzyme aldolase is choices B and C only: dihydroxyacetone phosphate and glyceraldehyde-3-phosphate. Hence, the answer to the question is E) choices B and C only.
