  • Oxidative decarboxylation  :Oxidative decarboxylation is an oxidation response where the carboxyl molecule is eliminated as carbon dioxide.During Kreb's cycle, the pyruvate is chemically changed to acetyl-CoA by decarboxylation in presence of the chemical pyruvate dehydrogenase enzyme.
  • Glycolysis is a metabolic pathway that breaks down glucose into pyruvate, generating ATP and NADH. The most common pathway of glycolysis is the Embden-Meyerhof-Parnas (EMP) pathway.The term glycolysis has originated from the Greek words, glycos for sugar, and lysis for splitting. The scheme of glycolysis was given by Gustav Embden, Otto Meyerhof, and J. Parnas, and is often referred to as the EMP pathway. In anaerobic organisms, it is the only process in respiration. Glycolysis occurs in the cytoplasm of the cell and is present in all living organisms. In this process, glucose undergoes partial oxidation to form two molecules of pyruvic acid
  • Oxidative phosphorylation is the process that synthesizes ATP by using energy derived from the transfer of electrons through a series of electron carriers in the electron transport system.
    Tricarboxylic acid: The TCA 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 and a molecule of CoA is released. Citrate is then isomerised to isocitrate.
