Question

What are the 2 coenzymes involved in TCA cycle?

Answer 1

TCA Cycle:

1. The Tricarboxylic acid (TCA) cycle is also called as Krebs or citric acid cycle.
2. It is the source of energy for cells and a vital part of aerobic respiration.
3. In this cycle, oxaloacetate is joined with acetyl-CoA to form citric acid.
4. The main function of the TCA cycle from the perspective of energy generation is to oxidize acetyl-CoA to two molecules of CO₂.
5. The TCA cycle generates two ATP molecules.

The two co-enzymes that work in the TCA cycle:

1. NAD (Nicotinamide Adenine Dinucleotide)
2. FAD (Flavin Adenine Dinucleotide)
