P6 Task 2 Metabolism
Metabolism is a system where it burns fat in your body by every movement you make. It burns calories through sleeping, sitting, exercising and standing. 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 into fatty acids, and carbohydrates into simple sugars (e.g., glucose). Furthermore the sugar, both amino acids and fatty acids can be used as energy sources by the body when needed. These compounds are absorbed into the blood, which transports them to the cells. After they enter the cells, other enzymes act to speed up or regulate the chemical reactions involved with "metabolising" these compounds. During these processes, the energy from these compounds can be released for use by the body or stored in body tissues, especially the liver, muscles, and body fat.
The fat is 98% efficient and so therefore 2% is wasted. Fats are stored under the skin and around organs as adipose tissue. Fats are made up of fatty acids and glycerol. Fibre efficiency is only 20%, and the 80% is wasted and used to digest this is because our body cannot digest fibre.
About 20% of the energy is used for the brain metabolism and the human body requires the energy by respiration. Other energy is used in basal
