What is it?
Metabolism is all the reactions that happen in the body, that is, refers to highly coordinated cellular activities that involves multienzymatic systems that act with each other to obtain chemical energy either solar or from nutrients, convert these nutrients into molecules whose structure is chemically available to cells, in addition to synthesizing and degrading molecules, that is, to act in catabolism and anabolism.
What’s it for?
Organisms extract energy from the environment and one of the functions of metabolism is to coordinate such extraction that is catalyzed by enzymes. it is from metabolism that energy from carbohydrates, proteins and lipids is removed and provided to the cells of the body so that they remain in full functioning.
How does it work?
Can be divided into canabolism, a process in which molecules are “broken” releasing energy, usually in the form of ATP (adenosine triphosphate), thenabolism that’s the opposite route to catabolism, that is, a path of “construction” in which molecules are formed from the energy expenditure. In addition to this classification, metabolic pathways can also be divided from the use or not of oxygen, being they vias of the maerobic etabolism that occur in the presence of oxygen or vanaerobic metabolism that occur when there is no presence of oxygen.
