Hi. We know that bond formation releases energy and bond break absorbs energy. I still don't figure out why ATP hydrolysis (that breaks a bond between oxygen and phosphorous) releases energy, and it releases a LOT.
ATP hydrolysis releases energy through the breaking of a high-energy bond between the second and third phosphate groups in ATP. This bond is unstable and when broken, releases energy that can be used for cellular processes.
ATP hydrolysis is considered an exergonic reaction because it releases energy. This energy is used to drive endergonic reactions, which require energy input, in the cell.
ATP serves as the primary energy currency of the cell. It provides energy for various cellular processes, such as muscle contraction, active transport, and biosynthesis.
ATP is able to store and release energy due to the unstable bond between the second and third phosphate groups. This bond is easily broken, releasing energy that can be used for cellular processes. ATP can also be reformed through the addition of a phosphate group, storing energy for later use.
Energy coupling is the process of using the energy released from exergonic reactions, such as ATP hydrolysis, to drive endergonic reactions. ATP hydrolysis releases energy that can be used to fuel cellular processes, making it an essential part of energy coupling in the cell.
