fosforüülimisele
Fosforüülimisele is a biological process involving the addition of a phosphate group to a molecule. This addition, catalyzed by enzymes called kinases, often serves to activate or deactivate a protein, or to store energy. It is a fundamental mechanism in cellular signaling and metabolism.
One of the most well-known examples of fosforüülimisele is the phosphorylation of adenosine diphosphate (ADP) to
In cellular signaling, phosphorylation acts as a molecular switch. When a signal is received, a cascade of
