Anaerobic reactions occurs in the ABSENCE OF OXYGEN ONLY, and involves the breakdown of sugar molecules into lactate and occurs in the CYTOSOL of activel skeletal muscles during movement
In contrast, aerobic reactions of respiration are reactions that occurs in the presence of oxygen ONLY, and involves the breakdown of sugar molecules into carbon dioxide, water and energy (in form of ATP). It occurs within the inner membrane of the mitochondria.
If there is lack of water that will reduce the amount of oxygen that the place give of and it will make everything colder because of the lack in water.
