  • Energy yields from Glycolysis
    • 4 molecules of ATP produced but 2 used in the initial phosphorylation of glucose. so net = 2 ATP
    • 2 molecules of reduced NAD (have potential to produce more ATP)
    • 2 molecules of pyruvate
    • The enzymes for glycolytic pathway are found in the cytoplasm so glycolysis does not require any organelle or membrane for it to take place
    • Does not require oxygen
    • In the absence of oxygen the pyruvate produced can be converted into lactate or ethanol by anaerobic respiration
    • Anaerobic respiration only produces a fraction of the energy stored in the pyruvate molecule
  • To release the remainder of the energy, organisms use oxygen to break down pyruvate > KREBS CYCLE
