This diagram shows the process of energy and human life. This may be a picture coming from a health magazine. It is generally true that this process is relatively simple and it is made up of three main stages. The whole process begins with chemical energy and ends in metabolism. The items used during the process include chemical energy (carbohydrates, fats and others), chemical waste (carbon dioxide, water), ATP (body’s energy currency), heat and metabolism. Overall, it is clear that energy and human life has become increasingly important over the years, and governments need to do something in order to encourage people to stay healthy. Overall, it is also clear that this process is beneficial and helps us to gain a better understanding of energy and human life.
