    Role of energy in the body why energy is necessary for the normal functioning of the body? Supplying enough energy to support the many functions of the body to work is one of the chief functions of food. This energy comes from the fats, carbohydrates, and proteins in the food we eat. Out of the three, fat is the most concentrated source of energy because it furnishes more than twice as much energy for a given weight as protein or carbohydrate .But the main form of energy for your body is carbohydrates

    Energy and Nutrition Cells release energy through an exergonic process called cellular respiration. Aerobic cellular respiration is a chemical process that uses oxygen to convert the chemical energy stored in food molecules into chemical energy that the cell can use, called ATP. Based on what I know about macromolecules (carbohydrates, fats, and protein) and energy, I think that my normal, daily dietary consumption is healthy on some days, but most days my diet is unhealthy. On a given
