How would you explain the connection between glucose entering the body and energy created by the body to a friend?

Glucose enters the body through carbohydrates ingested as part of our diets. It is then processed in the body through a series of steps involving a variety of enzymes. These steps include glycolysis, the citric acid cycle and electron transport. These enzymes convert glucose into a form of energy known as ATP that the cells use. This process is reversible with modification through a process called gluconeogenesis, self regulating (if there is too much ATP the process slows if there is too much glucose the process increases) and continuously occurring.
