Concept Introduction:
The series of reaction present in these reactions is called as
First the consumption of food gets digested which results in production of small molecules.
Glycolysis is a pathway which describes conversion of one molecule of glucose into 2
Pyruvate molecules. It involves totally 10 set of reactions with it.
Krebs cycle essentially involves the oxidation of acetyl CoA to
Citric Acid Cycle: It involves 8 series reaction which converts acetyl group present in acetyl coenzyme A into 2
