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.

- Biological oxidation: Oxidation in a series of reaction inside a cell.
- Cytochromes: A group of iron containing compounds of electron transport system present in inner wall of mitochondria.
- Dehydrogenase: Enzyme that catalyses removal of H atom from the substrate.
- Electron acceptor: Organic compound which receive electrons produced during oxidation-reduction reactions.
- Electron transport: Movement of electron from substrate to oxygen through respiratory chain during respiration.
- Respiration: Biochemical oxidation food to release energy.
- Respiratory Quotient: The ratio of the volume of CO2 produced to the volume of oxygen consumed.
- Proton gradient: Difference in proton concentration across the tissue membrane.
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.
