The sum of all biochemical reactions that take place in the human body at any given time is called .
a) phosphorylation
b) catabolism
c) anabolism
d) metabolism

d) metabolism

Explanation:

Metabolism is a set of chemical reactions that take place in the cells of the body. The metabolism transforms the energy contained in the food we eat into the fuel we need for everything we do, from moving to thinking to growing. These complex, interrelated processes are the basis of life on a molecular scale and enable the various activities of cells: growth, reproduction, maintenance of their structures and response to stimuli, among others. An organism's metabolism determines which substances it will find nutritious and which it will find toxic.

The metabolism is divided into two conjugated processes, catabolism and anabolism. Catabolic reactions release energy; an example of this is glycolysis, a process of degradation of compounds such as glucose, whose reaction results in the release of energy retained in their chemical bonds. Anabolic reactions, on the other hand, use this released energy to recompose chemical bonds and build cell components such as proteins and nucleic acids. Catabolism and anabolism are coupled processes since one depends on the other.

On the other hand, phosphorylation is the addition of a phosphate group to any other molecule. Its predominant role in biochemistry makes it an important object of research especially in the phosphorylation of proteins and fructose.
