I have a question related to both Biology and Chemistry. When I was at a PLF today for lifesci 7A, they said that when you break a bond, you go from high potential E to low potential E, which means that it is exergonic, because you release energy. However, I was told last quarter in chemistry that in order to break a bond it requires some energy. Therefore - I'm so confused which term is correct??
When a bond is broken it does release energy, but in order to break that bond, usually some amount of energy is needed. The amount released by breaking the bond tends to be more than what is needed to initiate the breaking of that bond.
In LS7A, we learned that the overall reaction would be exergonic, because it goes from a higher free energy to a lower free energy, thus resulting in a negative delta G. However, it is also true that breaking bonds requires energy.
