Question

In general, regulatory enzymes catalyze reactions that are irreversible in cells, that is, Reactions that are far from equilibrium. Why must this be the case?

Answer 1

ANS)  Regulatory enzymes catalyze reactions that are irreversible in cells and far from equlibrium because the switch response is so extensive and positive that typical variances in metabolite fixation don't influence the invert response to jump out at any considerable degree and due to this when they are a long way from equlibrium, irreversible responses become ideal focuses at which they control the motion through a metabolic pathway. For instance, multiplying the protein action could build the rate of the forward response significantly, yet would have little impact on the rate of the switch response.
