Question

Which step in the TCA cycle is related to the oxidative decarboxylation step?

Answer 1

The TCA cycle:

The metabolic activity that takes place aerobically in the mitochondria of organisms is known as the tricarboxylic acid (TCA) cycle, Krebs cycle, or citric acid cycle.
It is crucial to organisms because it provides cells with energy.

Step in the TCA cycle related to the oxidative decarboxylation step:

1. The process that leads to succinyl CoA production by -ketoglutarate is connected to oxidative decarboxylation.
2. The enzyme -ketoglutarate dehydrogenase catalyzes this process.
3. One molecule of CO2 is produced during the conversion of NAD+ to NADH.
4. This process results in the release of NADH, which serves as the respiratory chain's primary supply of electrons.
