2

Glycolysis

  • Also known as EMP pathway (Embden-Meyerhof-Parnas pathway)
  • Occurs in the cytoplasm of all living organisms
  • Glucose undergoes partial oxidation to form two molecules of pyruvic acid
3

  • Incomplete oxidation of glucose under anaerobic conditions
  • Two main types: alcoholic fermentation and lactic acid fermentation
  • Alcoholic fermentation: pyruvate → CO₂ + ethanol (in yeast)
4

Aerobic Respiration

  • Complete oxidation of organic substances in the presence of oxygen
  • Occurs in mitochondria of eukaryotic cells
  • Pyruvate is transported from cytoplasm to mitochondrial matrix
