A Catalyst increases the rate of reaction by providing alternative energy pathway ; usually increasing the rate of by 1012-1020. However it does not affect free energy ∆G (can’t make endergonic reaction go). Instead an enzyme can couple an exergonic reaction with an endergonic reaction via ATP breakdown. It will decrease EA for a spontaneous…
