Which of the following terms means the chemical addition of a phosphoryl group (PO3-) to an organic molecule.
A
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: -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-3: -Protein phosphorylation is defined as a covalent addition of the phosphate group to the side chain of tyrosine, serine, and threonine amino acid residues.

Detailed explanation-4: -Phosphorylation is a biochemical reaction where a phosphate group (PO4) is covalently bonded to another organic molecule. An example of phosphorylation is the addition of a phosphate to Adenosine Diphosphate (ADP) to form the molecule Adenosine Triphosphate (ATP).
