Question

Quizplus · Accepted Answer

During glycolysis, glucose is first phosphorylated twice by ATP, which requires an investment of two ATP molecules. The product of this reaction is a six-carbon molecule called fructose-1,6-bisphosphate, which is then split into two identical three-carbon compounds called phosphoglyceraldehyde (PGAL).
