Anaerobic respiration

• What happens after exercise?

  Heart rate remains high to pump oxygenated blood to replenish oxygen debt

  Lactate is converted to pyruvate or stored in the liver cells
• What occurs in lactate fermentation (humans)?

  • Pyruvate is reduced (accepts hydrogen from NADH) and converted to 2 lactates.
  • NADH is oxidised, allowing glycolysis to continue as they will be able to accept hydrogen from oxidation of triose phosphates
• What occurs in ethanol fermentation?

  • 2 pyruvate are decarboxylated to become ethanal.
  • Ethanal is reduced to form ethanol by accepting hydrogen from oxidation of NADH, so that glycolysis can continue
