The full form of FADH2 is Flavin adenine dinucleotide.
FADH2, along with NADH (Nicotinamide adenine dinucleotide), plays a crucial role in various metabolic processes, particularly in cellular respiration. According to the reference, both NADH and FADH2 are generated during the Krebs cycle. These molecules then contribute to the production of ATP (adenosine triphosphate) through oxidative phosphorylation.
Here's a breakdown of FADH2's role:
- Energy Production: FADH2 is a crucial electron carrier.
- Oxidative Phosphorylation: It delivers electrons to the electron transport chain, a key component of oxidative phosphorylation.
- ATP Generation: The reference states that FADH2 produces two ATP molecules through oxidative phosphorylation, compared to NADH, which generates three ATP molecules.
| Molecule | Full Form | Role in Cellular Respiration | ATP Yield (per molecule) |
|---|---|---|---|
| FADH2 | Flavin adenine dinucleotide | Electron carrier in oxidative phosphorylation | 2 |
| NADH | Nicotinamide adenine dinucleotide | Electron carrier in oxidative phosphorylation | 3 |
