Question

Explain the Krebs cycle with reaction.

Answer 1

1. The Krebs cycle was proposed by Hans Krebs; therefore, it is named the Krebs cycle. It is also known as the tricarboxylic acid (TCA) cycle or the citric acid cycle.
2. Acetyl coenzyme-A enters the mitochondria and participates in a series of cyclic chemical reactions known as the Krebs cycle.
3. These reactions bring about the complete oxidation of acetyl coenzyme-A and produce carbon dioxide CO₂, H₂O, NADH₂, FADH₂ and ATP.
