More to Know
  • Aerobic respiration: Complete oxidation of organic food in presence of oxygen thereby producing CO2, water and energy.
  • Anaerobic respiration: Incomplete breakdown of organic food to liberate energy in the absence of oxygen.
  • ATP Synthetize: An enzyme complex that catalysis synthesis of ATP during oxidative phospho-relation.
  • Fermentation: Breakdown of organic substance that takes place in certain microbe like yeast under anaerobic condition with the production of CO2 and ethanol.
  • Glycolysis: Enzymatic breakdown of glucose into pyruvic acid that occurs in the cytoplasm.
  • Oxidative phosphorylation: Process of formation of ATP from ADP and Pi using the energy from proton gradient.

Glycolysis

The term has originated from the Greek word, glycos = glucose, lysis = splitting, or breakdown means breakdown of glucose molecule to pyruvic acid. It was given by Embden Meyerhof and Parnas. It is a chain of 10 reactions to convert glucose into pyruvate. It is common for aerobic and anaerobic respiration.
