Aerobic: in general
1. occurs in presence of oxygen.
2. CO2 and water is produced
3. lot of energy is liberated (38 ATP)
4.occurs in plants' and animals' cells
5. C6H12O6 --> CO2 + H2O + ATP (Energy)
ATP from aerobic respiration of glucose
For longer periods of exercise muscle cells need oxygen supplied by the blood for aerobic respiration. This provides far more energy (36 molecules of ATP from each molecule of glucose), but the rate at which it can be produced is limited by how quickly oxygen can be provided. This is why you can’t run a marathon at the same speed as a sprint.
1. occurs in absence of oxygen
2. Lactic Acid or Alchol is produced
3. relatively small energy is liberated (2ATP)
4. occurs in many anaerobic bacteria and human muscle cells.
5. in muscles, lactic acid is produced while bacteria as Yeast produces Alcohol (Ethanol)
6. C6H12O6 --> Lactic acid / C2H5OH + ATP
ATP from anaerobic respiration of glucose
Anaerobic respiration doesn’t provide much ATP (2 ATP molecules for each glucose molecule),but it is quick, since it doesn’t require oxygen to be provided by the blood. It is used for muscle activities lasting a few minutes. There is not much glucose as such in muscle cells, but there is plenty of glycogen, which can be broken down quickly to make quite large amounts of glucose. The end product of anaerobic respiration is lactate, which gradually diffuses out of muscle cells into the blood and is carried to the liver. Here it is converted back to pyruvate.
In aerobic respiration the electron transport chain turns NADH back into NAD with the aid of oxygen and recycles the NAD. With anaerobic respiration the shortage of oxygen in the cells means that they must find another way to convert NADH back into NAD, this process is called fermentation. Lactate fermentation occurs in...
