Important Notes On Respiration In Plants

  • 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.


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.

Important Terms related to Chapter 14

  • 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.
