(b) Will Vmax for X be affected if Y is present in the reaction mixture? Explain. (a) No, X competes with Y for binding, so the apparent Km for X will stay the same. (b) Yes, the Vmax for X will decrease in the presence of Y. (a) No, Y does not compete with X for binding, so the apparent Km for X will stay the same. (b) No, the Vmax for X will be unaffected by the presence of Y.arrow_forward
