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.
Use of ATP usually does not lead to a decrease in ATP levels, due to the very rapid resynthesis. Extreme muscle activity leads to no more than a 20% reduction in ATP concentration in muscles. Only carbohydrates (glycogen or blood sugar) can be used anaerobically.Neither amino acids nor fatty acids can be processed without use of oxygen. Muscles differ in their ability to produce ATP through anaerobic and aerobic reactions. Fast-twitch white muscles with few mitochondria are the anaerobic fibers.nergy production, that is ATP synthesis from ADP and Pi, can occur anaerobically (without the use of oxygen) or aerobically (using mitochondrial reactions and oxygen). These reactions, especially anaerobic metabolism, are quite rapid.
