WebThe chemical equation that correctly summarizes the overall reaction in oxidative phosphorylation is A) H2 + O2 → H2O + O. B) 2 H2 + O2 → 2 H2O. C) 3 H2 + 2O2 → 3 H2O + 2 O. D) H2 + O2 → H2O. E) P + 3 O → PO3. B The function of the citric acid cycle is to A) remove hydrogen atoms from organic molecules and transfer them to coenzymes. WebGluconeogenesis is the synthesis of glucose. It is basically glycolysis run backwards; three new reactions (involving four new enzymes) make the standard free energy favorable. For every molecule of glucose synthesized from two molecules of pyruvate, 4 ATP, 2 GTP, and 2 NADH are used. WebJul 4, 2024 · In glycolysis and gluconeogenesis seven of the ten steps occur at or near equilibrium. In gluconeogenesis the conversion of pyruvate to PEP, the conversion of fructose-1,6-bP, and the conversion of glucose-6-P to glucose all occur very spontaneously which is why these processes are highly regulated. crystal amd

"WebNov 2, 2024 · The process of β -oxidation supports gluconeogenesis in two major ways: The NADH and FADH 2 generated from β -oxidation is oxidized in the electron transport chain to produce ATP. This ATP provides the needed energy for glucose synthesis. It also supplies energy to the urea cycle for nitrogen disposal. β -oxidation also produces acetyl-CoA.
