What process in the human body is referred to as energy metabolism?

The digestion process provides the human body with energy. When we eat food, it goes through several stages of processing. In the oral cavity, the process of splitting glucose begins with the help of certain enzymes. Also, the food is mixed. In the stomach, most substances are broken down into proteins, lipids, or carbons. Further, these substances begin to disintegrate into smaller ones. They provide us with energy. Therefore, you need to eat regularly and correctly so that the body receives the optimal amount of substances.
