Solution
The correct option is D Fructose-1,6-bisphosphate
The pathway of the breakdown of glucose into pyruvic acid is termed as glycolysis. This pathway is a step-wise process in which glucose (a hexose) is broken down into two pyruvate molecules (triose) via a series of reactions involving several intermediate compounds. The substrate for aldolase enzyme is fructose-1,6-bisphosphate (hexose). The enzyme aldolase converts fructose-1,6-bisphosphate into glyceraldehyde-3-phosphate and dihydroxyacetone phosphate, which are triose sugars and isomers of each other.
