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.
First, we need to know what ATP really is-chemically, it is known as adenosine triphosphate. ATP is a usable form of energy for cells-the energy is trapped in a chemical bond that can be released and used to drive other reactions that require energy (endergonic reactions).lycolysis-begins glucose metabolism in all cells to produce 2 molecules of pyruvate. Occurs outside of mitochondria, usually in cytoplasm. Cellular Respiration-uses oxygen from the environment and converts each pyruvate to three molecules of carbon dioxide while trapping the energy released in this process in ATP.
