Krebs Cycle is also known as which name?

Krebs Cycle is also known as which name?

• A. Tricarboxylic acid cycle (TCA).
• B. Glycolysis.
• C. Calvin cycle.
• D. Electron transport chain.

Answer: (A)

The Krebs cycle is also known as the tricarboxylic acid cycle because the first product formed in the cycle is citrate, a molecule that contains three carboxyl groups. This naming highlights the chemistry of the main substrate involved, distinguishing it from other pathways: glycolysis breaks down glucose in the cytosol, the Calvin cycle occurs in plants during photosynthesis, and the electron transport chain is the mitochondrial membrane system that uses the NADH and FADH2 produced by the cycle to generate ATP. So the best, widely used name for this pathway is the tricarboxylic acid cycle (TCA).
