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 energy released due to the oxidation of glucose [glucose: a simple sugar made by the body from food, which is used by cells to make energy in respiration] is used to synthesize ATP from adenosine diphosphate or ADP and inorganic phosphate or Pi. Fats and proteins can also be used as respiratory substrates.he energy released due to the oxidation of glucose [glucose: a simple sugar made by the body from food, which is used by cells to make energy in respiration] is used to synthesize ATP from adenosine diphosphate or ADP and inorganic phosphate or Pi.
