Answer:
Because the total energy of the enzyme has been used up and actions already complete
Explanation:
Catalyst are substance known to speed up rate of chemical reaction just like taking a short pathway. When velocity of catalyzed reaction reach maximum, at that moment reaction has reach it full potential (there is an equilibrium in reaction). there won't be any changes on further addition, and mostly indicate that Reaction is Complete
I'm pretty sure they come closer, and on the small chance i'm wrong, they separate.<span />
Answer: a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.
Explanation: definition
Yes if you add an energy to an electron the electron will become excited, and it will jump to its highest level then go back down releasing energy
