Book Chapter
Information on energy utilization from a section of the book "Energy" is presented. It emphasizes the importance of energy in performing everyday activities such as cycling, smiling and sleeping. It explains that the stomach turns the food one eat into a simple kind of sugar called glucose, while the muscles use the glucose and oxygen present in the body to make the energy they need when one moves. Potential energy is stored by foods in chemical form. There are different ways in which the body makes energy.
