What two 3-carbon molecules are generated by the cleavage of fructose-1,6-bisphosphate?
A) glyceraldehyde-3-phosphate and 3-phosphoglycerate
B) glyceraldehyde-3-phosphate and dihydroxyacetone phosphate
C) pyruvate and phosphoenolpyruvate
D) enolase and 2-phosphoglycerate
E) glyceraldehyde-3-phosphate and pyruvate

Question

Quizplus · Accepted Answer

The cleavage of fructose-1,6-bisphosphate during glycolysis produces two three-carbon molecules: glyceraldehyde-3-phosphate (G3P) and dihydroxyacetone phosphate (DHAP). DHAP can be isomerized to G3P, allowing both molecules to enter the same metabolic pathway.
