oxidation
B
phosphorylation
C
reduction
D
decarboxylation
Explanation: 

Detailed explanation-1: -The chemical addition of a phosphate group (PO3-) to an organic molecule is known as phosphorylation.

Detailed explanation-2: -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-3: -A process in which a phosphate group is added to a molecule, such as a sugar or a protein.

Detailed explanation-4: -Phosphoryl group derives from phosphoric acid and has an overall negative charge. Its chemical formula is PO32-. Phosphoryl group consists of a phosphorus atom in the centre and three oxygen atoms attached to it.

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