When you turn on a CD player, you are using this form of energy to produce sound energy. At a power plant nearby, matter is changed into energy to produce this form of energy. Eating a healthy breakfast provides this form of energy, which is turned into mechanical and thermal energy as you play, study, and move. Plug in a fan to a source of electrical energy. The electrical energy is transformed into this form to move the fan blades. Plug in a lamp into an electrical socket and you turn electrical energy into this form of energy. Radiant energy from the sun is turned into this form when plants undergo photosynthesis.
Our daily food choices resupply the potential energy, or fuel, that the body requires to continue to function normally. This energy takes three forms: carbohydrate, fat, and protein. (See table 2.1, Estimated Energy Stores in Humans.) The body can store some of these fuels in a form that offers muscles an immediate source of energy. Carbohydrates, such as sugar and starch, for example, are readily broken down into glucose, the bodyâs principal energy source. Glucose can be used immediately as fuel, or can be sent to the liver and muscles and stored as glycogen.
