Here's a breakdown:
* High-energy bonds are chemical bonds that store a significant amount of potential energy. These bonds are typically found in molecules like ATP (adenosine triphosphate).
* Hydrolysis is a chemical reaction where water is used to break a bond.
* When a high-energy bond is broken during hydrolysis, the energy stored in that bond is released. This energy can then be used to power other cellular processes.
Example:
In the case of ATP, when the bond between the second and third phosphate groups is broken by hydrolysis, a large amount of energy is released. This energy can be used for processes like muscle contraction, protein synthesis, or active transport.
So, to correct the statement:
High-energy bonds release a large amount of free energy when broken during hydrolysis, not when the phosphate group is attached.
