I'm new to the subject and i have an intuition that during the time the substrate and the enzyme are together energy is transferred to the substrate (from the enzyme) to break the bonds and to release the substrates energy*. But alas i have been met with opposition to this understanding, both times being presented with what seemed to be a quote, saying: "Why would the enzyme be needed to break down a molecule if the molecule it was breaking down already had the energy it needed to break itself down?" Which i think is completely illogical because its like saying: "Why would a person be needed to push a boulder off a cliff, if the boulder already has the energy it needed to push itself down?" Could anyone help enhance my understanding? *The reason i believe this is possible is because after the enzyme gives energy to the substrate the substrate thus releases even more energy which somehow "recharges" the enzyme.
