However, cannabis is more commonly known as the source of the marijuana drug, although the word marijuana applies both to the whole plant, and to the resin from it (although this is sometimes also called hashish).
Malate is oxidized to oxaloacetate, reducing NAD + to NADH 2 + . We are now back at the beginning of the Krebs Cycle. Because glycolysis produces two pyruvate molecules from one glucose, each glucose is processes through the kreb cycle twice. For each molecule of glucose, six NADH 2 + , two FADH 2, and two ATP.
One glucose molecule produces four ATP, two NADH, and two pyruvate molecules during glycolysis. Learning Objective. Key Points. Although four ATP molecules are produced in the second half, the net gain of glycolysis is only two ATP because two ATP molecules are used in the first half of glycolysis.
