M2: Discuss the probable homeostasis responses to changes in the internal environment during exercise
Homeostasis is the process by which the internal environment of the body is kept relatively stable despite changes in the environment. Your body is able to adapt to several different conditions. When exercising you become a little bit acidic because lactic acid accumulates in your tissues (especially muscles) due to glucose metabolism (to produce energy), because of this, your breathing becomes faster to eliminate CO2 which also causes acidity. Your heart rate increases in order to pump more oxygenated blood around the body. Another factor is heat, because your body uses energy up, body temperature is increasing and overheating is prevented through sweating which cools your body down. When you sweat, you lose some water, this signal is received by the brain's thirst centre and so it makes you feel thirsty and want to drink.
The blood glucose level will increase during exercise if there is not enough insulin. Muscles hold enough energy for a short amount of exercise. After that, they rely on increased blood supply to deliver oxygen, blood sugar and other nutrients to maintain more energy. Your body burns the sugar in your blood, and then tries to regain more from your liver to supply stored glucose to keep up with energy levels. As you warm up, your muscles start to try finding nutrients to make energy. Glucose carried in your blood and delivered to the muscles is an energy supply, as are free fatty acids, a type of lipid carried in blood that provide energy when glucose is low. Using energy during exercise helps balance high blood sugar and provide fuel at the same time. As blood flow to your muscles increases, the energy supplies increase as well.
During exercise, the muscle cells respire more than they do at rest. This means, oxygen and glucose must be delivered to them more quickly and waste carbon dioxide must be removed more quickly. This is achieved by increasing the breathing rate

Without metabolism life would be unable to survive or yet even exist. It is the chemical reaction in the body that helps anything that is living survive. This is mostly seen when the food that has been consumed is turned into energy that is need for the daily activities. Metabolism is carried out enzymes, if the enzymes are more productive or working faster than metabolism will be high but if they are slow them metabolism will be low, which is not good because if the enzymes stop the whole body…

form of energy. When you think of aerobic and anaerobic exercises, you should really think of them in the mind frame of the presence of oxygen. In aerobic exercises, your body is using oxygen to create energy (Callaway, 2011). In anaerobic exercises, your body is using everything but oxygen to create energy (Callaway, 2011). Strictly speaking, the terms "aerobic" and "anaerobic" refer to the presence and absence of oxygen, respectively. Most of our cells prefer to get their energy by using…

REGULATION OF FAT METABOLISM DURING EXERCISE The fat generally make less energy than carbohydrate to muscle’s needs during exercise, mobilization and oxidation of FFAs are critical to performance in endurance exercise. During such long activity, carbohydrate reserves become depleted, and muscle must rely more on the oxidation of fat for energy production. When carbohydrate reserves are low (low plasma glucose and low muscle glycogen), the endocrine system can accelerate the oxidation of fats (lipolysis)…

We get the energy out of the food we take in and digest which is then broken down to release energy. The energy is required for respiration which is used to make protein, convert fats into lipids and develop cells. After food is eaten, molecules in the digestive system called enzymes break proteins down into amino acids, fats…
