BC: Fermentation. | Fermentation complements glycolysis and makes it possible for ATP to be continually produced in the absence of oxygen. By oxidizing the NADH produced in glycolysis, fermentation regenerates NAD+, which can take part in glycolysis once again to produce more ATP.
1: 1. Krebs Cycle 2. Glycolysis 3. aerobic respiration 4. anaerobic respiration 5. fermentation (alcoholic/latic acid)
2: Krebs cycle. | produces CO2 & NAD & FAD | Then after passing through the electron transport chain NAD & FAD help produce ATP
3: Glycolysis. | It occurs in virtually all cells. In eukaryotes, it occurs in the cytosol. C6H12O6 + 2NAD+ -> 2C3H4O3 + 2NADH + 2H+ The free energy stored in 2 molecules of pyruvic acid is somewhat less than that in the original glucose molecule. Some of this difference is captured in 2 molecules of ATP.
4: aerobic respiration. | Aerobic respiration is the release of energy from glucose or another organic substrate in the presence of Oxygen. Strictly speaking aerobic means in air, but it is the Oxygen in the air which is necessary for aerobic respiration. Anaerobic respiration is in the absence of air.
5: anaerobic respiration. | In the case of anaerobic respiration, glucose is broken and the products generated from this are energy and either lactic acid or ethanol (alcohol) and CO2. This process is termed as fermentation
