Detailed explanation-1: -Phosphorylation is the addition of a phosphoryl (PO3) group to a molecule. In biological systems, this reaction is vital for the cellular storage and transfer of free energy using energy carrier molecules.

Detailed explanation-2: -Phosphorylation is the addition of a phosphate (PO4) group to a protein molecule or a small molecule. It can also be thought of as the introduction of a phosphate group into an organic molecule.

Detailed explanation-3: -We can define phosphorylation as a biochemical process in which a phosphate molecule is added to some organic compound, such as glucose and adenosine diphosphate (ADP).

Detailed explanation-4: -Phosphorylation: A biochemical process that involves the addition of phosphate to an organic compound. Examples include the addition of phosphate to glucose to produce glucose monophosphate and the addition of phosphate to adenosine diphosphate (ADP) to form adenosine triphosphate (ATP).

Detailed explanation-5: -There are three phosphorylation mechanisms – 1) substrate level; 2) oxidative; and 3) photophosphorylation.
