Explanation:
Preparatory step often shorten to prep step occurs just after glycolysis. It takes place in mitochondrial matrix. It basically involves following reaction:
- Pyruvic acid i.e a 3-carbon molecule undergoes decarboxylation (removal of
#CO_2# ) and is converted into 2-carbon molecule i.e acetic acid. Acetic acid then enters the mitochondrion where it unites with#"acetyl coenzyme-A"# to form#"active acetate i.e acetyl CoA"# . The acetyl CoA is end product of preparatory step which then enters the cyclic series of Krebs cycle.
