Answers. They make ATP from ADP. Oxidation Phosphorylation. They create ATP synthase. By definition, oxidative phosphorylation is the process by which electrons from NADH and FADH2 are transferred to O2 molecules through a series of electron carriers/protein complexes in order to generate ATP from ADP for the cell's energetic needs. The Citric Acid Cycle. 1,5-dihydro-FAD. FADH2 is also made. 2021-01-16.

They Communicate Information Between All The Stages Of Cellular Respiration To Ensure Every Part Works Together. NADH and FADH2 are both produced during the Krebs Cycle, which is the second part of cellular respiration. To Produce Acetyl CO-A B. 7. What is the key difference between these molecules in terms of energy producing capacity? What do they contribute to cellular respiration? The electrons from these molecules are then used in the electron chain during oxidative phosphorylation (the third part of cellular respiration). What is the role/function of NADH and FADH2? It is a conjugate acid of a FADH2(2-). Oxidative Phosphorylation. Solution for What is the value of NADH and FADH2? rmathias485. 2 Names and … They donate electrons by providing hydrogen molecule to the oxygen molecule to create water during the electron transport chain.
