- Absence of oxygen
- Neither the Krebs or electron transfer chain can continue because soon all the FAD and NAD will be reduced
- No FAD or NAD will be available to take up the H+ produced during the Krebs cycle and so the enzymes stop working
- This leaves only the anaerobic process of glycolysis as a potential source of ATP
- The replenishment of NAD is achieved by the pyruvate molecule from glycolysis accepting the hydrogen from reduced NAD
- The oxidised NAD produced can then be used in further glycolysis
Production of ethanol in plants and some microorganisms:
- Occurs in organims such as bacteria and fungi (yeast)
- The pyruvate molecule formed at the end of glycolysis loses a molecule of crabon dioxide and accepts hydrogen from reduced NAD to produce ethanol
pyruvate + reduced NAD -> ethanol + carbin dioxide + oxidised NAD
Production of lactate in animals:
- Occurs most commonly in muscles as a result…
