Topics in Respiration in Plants

1

1. Respiration and Gas Exchange in Plants

  • Plants need oxygen for respiration and release carbon dioxide.
  • Plants do not have specialised respiratory organs, but stomata and lenticels help in gas exchange.
  • Gas exchange is easy in plants because most living cells are close to the surface.
2

2. Glycolysis

  • Glycolysis is the breakdown of glucose into two molecules of pyruvic acid.
  • It occurs in the cytoplasm and is present in all living organisms.
  • It is also called the EMP pathway, named after Gustav Embden, Otto Meyerhof, and J. Parnas.

3. Fate of Pyruvic Acid

  • Pyruvic acid is the key end product of glycolysis.
  • Its fate depends on cellular need and oxygen availability.
  • There are three major ways cells handle pyruvic acid: lactic acid fermentation, alcoholic fermentation, and aerobic respiration.
4

4. Aerobic Respiration and the TCA Cycle

  • Aerobic respiration is the complete oxidation of organic substances in the presence of oxygen.
  • It occurs in mitochondria in eukaryotes.
  • Pyruvic acid enters the mitochondrial matrix and undergoes oxidative decarboxylation to form acetyl CoA.
