  1. H H Pi Pi Pi A The protons are combined with the electrons and oxygen…. O

  2. H H Pi Pi Pi A ….to form a molecule of water O

  3. H H H H H H H H H H H H Pi Pi Pi A In the absence of oxygen, there is a build up of hydrogen atoms

  4. H+ H+ H H H+ H H H+ H H H H H H H+ H+ H+ H+ H H Pi Pi Pi A The NADH/H+ and FADH2 will not be reoxidised as they will no longer be able to release the Hydrogen they are carrying

  5. H H+ H H H+ H H H+ H H+ H H+ H H H H H+ H H H+ H+ H Pi Pi Pi A NAD The NADH/H+ and FADH2 will not be reoxidised as they will no longer be able to release the Hydrogen they are carrying

  7. This means that respiration cannot proceed beyond the first stage – glycolysis.

  8. This means that respiration cannot proceed beyond the first stage – glycolysis.

  9. This means that respiration cannot proceed beyond the first stage – glycolysis. The pyruvate accepts hydrogen atoms from the NADH/H+ directly in animals

  10. This means that respiration cannot proceed beyond the first stage – glycolysis. The pyruvate accepts hydrogen atoms from the NADH/H+ directly in animals

  11. H H+ This means that respiration cannot proceed beyond the first stage – glycolysis. NAD The pyruvate accepts hydrogen atoms from the NADH/H+ directly in animals

  12. H H+ This means that respiration cannot proceed beyond the first stage – glycolysis. NAD The pyruvate accepts hydrogen atoms from the NADH/H+ directly in animals

  13. H H+ This means that respiration cannot proceed beyond the first stage – glycolysis. NAD The pyruvate accepts hydrogen atoms from the NADH/H+ directly in animals

  14. H H This means that respiration cannot proceed beyond the first stage – glycolysis. NAD The pyruvate accepts hydrogen atoms from the NADH/H+ directly in animals

  15. H H This means that respiration cannot proceed beyond the first stage – glycolysis. NAD The pyruvate accepts hydrogen atoms from the NADH/H+ directly in animals and forms lactic acid.

  16. H H This means that respiration cannot proceed beyond the first stage – glycolysis. NAD A considerable amount of energy is trapped in the lactic acid.

  17. This means that respiration cannot proceed beyond the first stage – glycolysis. In plants the pyruvate is first decarboxylated to release CO2

  18. O C O This means that respiration cannot proceed beyond the first stage – glycolysis. In plants the pyruvate is first decarboxylated to release CO2

  19. O C O This means that respiration cannot proceed beyond the first stage – glycolysis. In plants the pyruvate is first decarboxylated to release CO2

  20. O C O This means that respiration cannot proceed beyond the first stage – glycolysis. In plants the pyruvate is first decarboxylated to release CO2

  21. O C O This means that respiration cannot proceed beyond the first stage – glycolysis. The 2C intermediate accepts the hydrogen atoms from NADH/H+ and forms ethanol

  22. O H H+ C O This means that respiration cannot proceed beyond the first stage – glycolysis. NAD The 2C intermediate accepts the hydrogen atoms from NADH/H+ and forms ethanol

  23. O H H+ C O This means that respiration cannot proceed beyond the first stage – glycolysis. NAD The 2C intermediate accepts the hydrogen atoms from NADH/H+ and forms ethanol

  24. O H H+ C O This means that respiration cannot proceed beyond the first stage – glycolysis. NAD The 2C intermediate accepts the hydrogen atoms from NADH/H+ and forms ethanol

  25. O H H+ C O This means that respiration cannot proceed beyond the first stage – glycolysis. NAD The 2C intermediate accepts the hydrogen atoms from NADH/H+ and forms ethanol

  26. O H H+ C O This means that respiration cannot proceed beyond the first stage – glycolysis. NAD The 2C intermediate accepts the hydrogen atoms from NADH/H+ and forms ethanol

  27. O H H+ C O This means that respiration cannot proceed beyond the first stage – glycolysis. NAD A considerable amount of energy is trapped in the ethanol

  28. In animals the pyruvate is converted to lactic acid: Glucose
