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.
Glucose (sugar) only = carbon dioxide + lactic acid + some energy In anaerobic respiration only the first stage of sugar breakdown occurs. Lactic acid builds up in the muscles and stops them working. The person breathes faster to take in more oxygen so that lactic acid can be broken down to carbon dioxide and water.hen muscles are working hard, they use up a lot of oxygen. If oxygen does not get to the muscles fast enough for aerobic respiration, the muscles change to anaerobic respiration by processing only the first stage of glucose breakdown and making lactic acid instead.
