In the aldol cleavage of Fructose 1,6 bis phosphate to DHAP and GAP, why is there 96% DHAP?
Answer: Because DHAP is involved in the uptake of glycolysis NADH electrons into the mitochondrial matrix so they can also be used in ATP production. BUT these are taken up by FADH molecules and so become worth only 1.5 ATP (unlike Krebs Cycle NADHs)
