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.
Describe how energy is stored in ATP. Explain why ATP is a good energy storage molecule. Discuss different ways cells use ATP. Question 1: What does ATP contain? 1) ribose sugar 2) adenine 3) alanine 4) three phosphate groups 5) a phosphate group _____ Question 2: Which of the covalent bonds in ATP are mainly used for energy in cell processes?
