metabolism

Is a series of biochemical reactions that occur in living cells. Kinds of metabolism:

1. Catabolism, is the process of breaking complex molecules into simpler molecules to release energy (ATP). Example: respiration, amino acid dismantling, demolition of ATP, glycogenolysis fat demolition.

2. Anabolism, is the process of formation of complex molecules from simple molecules that requires energy. Example: photosynthesis, protein synthesis, glycogenesis, ATP synthesis, the preparation of fat.
