What is phosphorylation?

Phosphorylation: A biochemical process that involves the addition of phosphate to an organic compound. The addition of phosphate to glucose to produce glucose monophosphate and the addition of phosphate to adenosine diphosphate (ADP) to form adenosine triphosphate (ATP) are the examples for phosphorylation. Phosphorylation plays critical roles in the regulation of many cellular processes including cell cycle, growth and apoptosis. Three of the most important types of phosphorylation are glucose phosphorylation, protein phosphorylation, and oxidative phosphorylation.
