Question

Regarding the reaction pathway of the citric acid cycle:

what are the energy producing steps in the cycle?

Answer 1

The citric acid cycle is also known as TCA cycle or Krebs cycle. This cycle is a series of used by iall aerobic organisms to generate energy.

This is a series of reactions that produces 2 CO2, 1 GTP/ATP, 1 FADH2 and 3 NADH2.

Energy producing steps in the cycle.

1. Isocitrate -------->a-ketogluterate, NADH2 formed, co2 released

2. a-ketogluterate------>succinyl coA, NADH2 and co2 released

3.succinyl coA ---------> succinate, GTP released

4.succinate------------> fumerate, FADH2 released

5.malate----------> oxaloacetate, NADH2 released

From reduced forms of NADH2 and FADH2 energy is released in the form of ATP in ETC in mitochondria.
