What is the reaction logic behind converting glucose 6-phosphate to fructose 6-phosphate in the preparatory phase of glycolysis? Moving the carbonyl allows for the formation of an electron sink in a position where fructose 1,6 bisphosphate can be split into two three-carbon units by aldolase. 4. In anaerobic organisms, how is the NAD + consumed in glycolysis regenerated? Lactate dehydrogenase regenerates NAD + by converting pyruvate into lactic acid. Alcohol dehydrogenase regenerates NAD + by converting acetaldehyde into ethanol. Each of these enzymes utilizes NADH as a reducing agent. 5. How many NADH and FADH 2 molecules are generated through the -oxidation of palmitic acid to acetyl-CoA? How many molecules of acetyl-CoA are generated? 7 NADH, 7 FADH 2 , and 8 acetyl-CoA are generated....
