Changes in bond energy quick check quizlet
WebATP has potential energy in the bonds between the phosphates. If an ATP molecule is used, one phosphate is 'broken' off and so the bond between the phosphates is broken. There was energy stored in this bond, which is then used to do numerous kinds of things in your … WebBond energy is the measure of a bond’s strength; the bigger the bond energy, the stronger the chemical bond. If the bond energy of a chemical bond is negative, the bond cannot exist because it will be too unstable. Therefore, it is almost impossible for a chemical bond to have a negative value for its bond energy.
