We get the energy from food, such as fats, carbohydrates and proteins. Our body then absorbs the energy from the foods as it goes through the digestive system and it diffuses into our bloodstream [1]. The energy helps us to move our muscles, walk and talk; without the energy in our body we would not be able to do basic things. “It cannot be created or destroyed but can only be changed from one type to another.” [2] Metabolism Metabolism is a collection of chemical reactions that take place in the cells of a human body. They help to sustain life. It converts the carbohydrates, fats and proteins into energy that our body absorbs. Metabolic rate is how fast or slow a person burns off the energy that they get from food whilst at rest, this can determined whether the person puts on weight or loses weight. [3] Anabolism 6 6 Anabolism often called Constructive metabolism or biosynthesis is the building up of things.
