The Citric Acid Cycle (Krebs) | Step by step explanation

The Krebs Cycle is the final route of various oxidation reactions for Carbohydrates, Lipids and Porteins. This is because both Glucose, fatty acids and most amino acids are oxidized to Acetyl-CoA. Which, as we already learned, is the precursor for the formation of Citrate or Citric Acid.

In one Krebs cycle decarboxylation takes place at steps

Hint: Decarboxylation is the process of removal of the carboxyl group from a compound with the release of a carbon dioxide molecule. So, the nuer of steps in which a ${C}{O}_{2}$ molecule is released after removal of a carboxyl from a compound is the nuer of decarboxylation reactions in one Krebs’ cycle.
