What is the source of energy for the formation of ATP and NADH in glycolysis 17. A total of three ATP are produced for every NADH molecule and two ATP for every FADH, molecule. WebThe video claims that acetyl-coa from fatty acid oxidation cannot contribute to gluconeogenesis because the pyruvate dehydrogenase step is irreversible. Hypothetically acetyl coa could enter the TCA and become OAA. That OAA can be converted to phosphoenolpyruvate (PEP) by PEP carboxylase. The PEP can be converted to glucose …
