Like many other members of the B-vitamin family, Niacin is well-known for its role in energy metabolism (breaking down substances in the body to yield energy). Actually, niacin plays a part in the energy metabolism of all cells in the body. Another benefit of water-soluble vitamin is its versatility.
Adenosine triphosphate (ATP) , the energy currency or coin of the cell pictured in Figfures 1 and 2, transfers energy from chemical bonds to endergonic (energy absorbing) reactions within the cell.nergy is stored in the covalent bonds between phosphates, with the greatest amount of energy (approximately 7 kcal/mole) in the bond between the second and third phosphate groups. This covalent bond is known as a pyrophosphate bond.
ATP is the molecule that cells use to get their energy. ATP is  produced either by photosynthesis or by cell respiration. Edit. Share to: 1  The Five Major Parts of the Brain At its most basic, the brain controls the body.uring cellular respiration energy is stored in ATP molecules. When ATP is converted in to ADP, this energy is released for cells to use. The conversion of ADP in to ATP requi â¦ res molecules of hexose sugar to break down.
