Problem 2: Products of Glycolysis
At the end of glycolysis, each molecule of glucose has yielded 2 molecules of _______, 2 molecules of ________, and a net of 2 molecules of _________.
A. FAD; NAD+; ADP
B. CO2; NAD+; ADP
C. lactic acid; ethanol; CO2
D. pyruvate; NADH; ATP
E. H2O; CO2; ATP
Molecules converted in glycolysis
Glycolysis is a series of 10 reactions requiring two molecules of ATP to convert glucose to activated intermediates, followed by cleavage and conversions to two molecules of pyruvate. The summary below of glycolysis shows that the process produces two molecules of NADH and four molecules of ATP for a net yield of 2 ATP.

ans:
D. pyruvate; NADH; ATP
Glycolysis is the conversion of glucose to two molecules of pyruvate, yielding a net 2 ATP and 2 NADH. Recall that 2 ATP were needed to initiate glycolysis and 4 ATP were produced in the pathway, for a net gain of 2 ATP.
