Question

Is NADH an electron carrier?

Answer 1

Electron carrier

1. During the electron transport process, a molecule capable of absorbing one (or more) electrons from another molecule (electron donor) and then ferrying these electrons to give to another is known as an electron carrier.

NADH (Nicotinamide adenine dinucleotide):

1. The coenzyme nicotinamide adenine dinucleotide is essential for metabolism.
2. NAD is a dinucleotide that is found in all living cells and is made up of two nucleotides connected by their phosphate groups.
3. Electron carriers can be compared as shuttles for electrons.
4. These compounds can easily take electrons (i.e., they can be reduced) or lose them (i.e., they can be oxidized) (i.e., be oxidized).
5. Because cellular respiration is dependent on the passage of electrons, they play an important role in energy production.
6. Glucose is broken down into carbon dioxide and water during the various stages of cellular respiration.
7. Electron carriers pick up electrons that have been lost by glucose during these processes, momentarily store them, and then feed them into the electron transport chain.
8. NAD+ and FAD, both produced from B vitamins, are two such electron transporters.
9. Earlier steps of cellular respiration create the reduced forms of NAD+ and FAD, NADH, and FADH2, respectively (glycolysis, pyruvate oxidation, and the citric acid cycle).
