They are not categorical (like male and female), that are not discrete (like number of people in a single car; you would not typically think about 3.5 people in a car).
Aerobic exercise. Aerobic exercise means that muscles use up a lot of glucose as a fuel and tends to lower blood glucose levels. Anaerobic exercise involves higher rates of muscle contraction for shorter periods of time.naerobic exercise uses different body systems to generate fuel and is usually associated with release of chemicals (counter-regulatory hormones) that block the action of insulin and turn the liver on to make more glucose â this can mean that this type of exercise causes blood glucose levels to rise.
During hard exercise, anaerobic respiration Anaerobic respiration: respiration that occurs in the absence of oxygen takes place as well as aerobic respiration. Anaerobic respiration does not need oxygen for it to happen: Glucose â lactic acid.The waste product, lactic acid, builds up in the muscles causing pain and tiredness. Anaerobic respiration releases much less energy per glucose molecule than aerobic respiration does.lucose â lactic acid. The waste product, lactic acid, builds up in the muscles causing pain and tiredness. Anaerobic respiration releases much less energy per glucose molecule than aerobic respiration does.
