Energy is always required to break bonds and always is released when bonds are formed, even with ATP, but the part that is omitted is that more molecules of water are bound and ordered after the ATP hydrolysis than before and so more ordering plus many more highly energetic hydrogen bonds formed than broken equals a large overall release of energy for the overall process.
The change in free energy (triangle G) is positive and the products have more free energy than the reactants - can only occur if there is an input of energy. ATP is _____. A nucleotide composed of the nitrogen-containing based adenine and the 5-carbon sugar ribose (together called adenosine) and three phosphate groups. Often called a high energy compound because a phosphate group can easily be removed. Coupled reactions Energy released by an exergonic reaction is used to drive an endergonic reaction - ATP is often coupled to cellular reactions that require an input of energy. Function of ATP in Chemical work ATP supplies the energy needed to synthesize macromolecules that make up the cell, and therefore the organism.
