Nice and useful information, I work as a professor of physical and athletic education, and I need a lot of this information.
Living beings in all their forms need energy to sustain their lives, and humans also need great energy to carry out all their vital and kinetic processes in their bodies. Man derives his energy from food, but is not ready to consume it as energy within the body, it must be converted into energy through a process called metabolism or metabolism. Without this process, humans can not benefit from the food they eat.
Metabolism is one of the vital processes that occur within the human body and organisms in general. It is responsible for producing energy within the cells of the body by destroying the nutrients digested within the digestive system and converting them into different forms of energy by passing through a series of reactions Chemical, and metabolism is the process by which different cells and tissues are constructed and destroyed.
Finally thank you dear @rtonline for providing this wonderful information.
