Question
 Explain the Krebs cycle with reaction.
✓

Answer

  • Krebs cycle was proposed by Sir Hans Kreb. This cycle is named after him. It is also called 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 Krebs cycle.
  • In the cyclic chemical reactions, acetyl- coenzyme-A is completely oxidised
  • It yields molecules of $CO_2, H_2O, NADH_2, FADH_2$ and $ATP$ upon complete oxidation.
