MUSCLE PHYSIOLOGY

Detailed explanation-1: -The chemical addition of a phosphate group (PO3-) to an organic molecule is known as phosphorylation. Phosphorylation is carried out by enzymes known as phosphotransferases or kinases. A phosphotransferase is an enzyme that catalyzes the addition of a phosphate group.

Detailed explanation-2: -phosphorylation, in chemistry, the addition of a phosphoryl group (PO32-) to an organic compound. The process by which much of the energy in foods is conserved and made available to the cell is called oxidative phosphorylation (see cellular respiration).

Detailed explanation-3: -Phosphorylation adds a phosphate group to serine, threonine, and tyrosine residues in a protein, changing their shapes, and activating or inactivating the protein . In protein phosphorylation, a phosphate group is added to residues of the amino acids serine, threonine, and tyrosine.
