It is also plays vital roles in carbohydrate metabolism, fat metabolism, protein synthesis and repair of worn out tissues. Oxygen on the other hand is required for oxidation of biological fuel and for breathing.
Phosphates are usually formed from one atom of phosphorus and four atoms of oxygen, it has the chemical formula PO4. Phosphate is an important component of DNA and RNA molecules, phosphates hold these molecules together. Phosphate molecule is also found in ATP, which is the energy currency of living cells.
