NAD+ is a CO-enzyme.
One NADH molecule generates approximately 2.5 to 3 ATP through oxidative phosphorylation in the mitochondria.
NADH can be recycled to NAD through the process of oxidative phosphorylation in mitochondria. During this process, NADH donates its electrons to the electron transport chain, leading to the generation of ATP and the conversion of NADH back to NAD+.
NADH produces 3 ATPs because it donates the proton at a "higher" location in the electron transport chain than does FADH2, which is why FADH2 produce only 2 ATPs. NADH and FADH2 donates electrons and protons into the electron transport chain.
10 NADH molecules are produced in total. 2 during glycolysis, 2 during link reaction (1 per pyruvate, 2 per glucose molecule), and 6 during the Krebs cycle. None during the electron transport chain.
When a molecule of NAD gains a hydrogen atom, it becomes reduced to form NADH (nicotinamide adenine dinucleotide). This reduction reaction involves the transfer of electrons from the hydrogen atom to NAD, resulting in the formation of NADH.
The NADH produced in glycolysis enters the electron transport chain (ETC) at a lower energy level compared to the NADH produced in the Krebs cycle. This difference in energy level leads to a smaller proton gradient and ultimately results in the production of less ATP when the NADH from glycolysis is used in the ETC.
Molecules that donate electrons to the electron transport chain include NADH and FADH2, which are produced during glycolysis and the citric acid cycle. These molecules transfer their electrons to protein complexes in the electron transport chain, ultimately leading to the production of ATP through oxidative phosphorylation.
NADH is a coenzyme form of vitamin B3 that plays a key role in cellular energy production. It acts as a carrier of electrons in the electron transport chain, helping to generate ATP, the energy currency of the cell. Its reduced form, NADH, donates electrons to the chain to drive the production of ATP.
In the electron transport chain, the molecules that enter are NADH and FADH2. These molecules donate their electrons to the chain, which then pass along a series of protein complexes in the inner mitochondrial membrane to generate ATP through oxidative phosphorylation.

NADH can be recycled to NAD through the process of oxidative phosphorylation in mitochondria. During this process, NADH donates its electrons to the electron transport chain, leading to the generation of ATP and the conversion of NADH back to NAD+.
Two molecules of NADH are generated after one cycle of the TCA (Krebs) cycle.
10 NADH molecules are produced in total. 2 during glycolysis, 2 during link reaction (1 per pyruvate, 2 per glucose molecule), and 6 during the Krebs cycle. None during the electron transport chain.

NADH and H play a crucial role in the electron transport chain during cellular respiration. NADH donates electrons to the chain, which then pass through a series of protein complexes, generating energy in the form of ATP. The presence of H ions helps create a gradient across the inner mitochondrial membrane, driving the production of ATP through a process called chemiosmosis. Overall, NADH and H are essential for the efficient functioning of the electron transport chain in producing energy for the cell.
