Solution

Oxidative decarboxylation
  • Pyruvate, the end product of glycolysis, undergoes oxidative decarboxylation to form acetyl-CoA and release CO2. The enzyme is called pyruvate dehydrogenase.
  • Pyruvate + CoA + NAD+ →Pyruvate dehydrogenaseMg+2 Acetyl-CoA + CO2 + NADH.H+ 
Glycolysis
  • The process common for aerobic and anaerobic respiration.
  • This is also called EMP or Embden, Meyerhof, and Parnas pathway.
  • The glucose is converted into 3-carbon pyruvic acid.
Oxidative phosphorylation
  • The formation of ATP in the mitochondria is called oxidative phosphorylation. This is accomplished through ETS.
Tricarboxylic acid cycle
  • The TCA (tricarboxylic acid cycle) starts with the condensation of acetyl group with oxaloacetic acid
    (OAA) and water to yield citric acid. The reaction is catalysed by the enzyme citrate synthase.
