Question

Explain the Krebs cycle with reaction.

Answer 1

• Krebs cycle was proposed by Sir Hans Kreb. This cycle is named after him. It is also called the tricarboxylic acid cycle or citric acid cycle.
• The acetyl-coenzyme-A molecules enter the mitochondria located in the cytoplasm.
• They participate in the chemical reactions taking place in the Krebs cycle.
• In the cyclic chemical reactions, acetyl- coenzyme-A is completely oxidised
• It yields molecules of CO₂, H₂O, NADH₂, FADH₂, and ATP upon complete oxidation.
