Answer» 1. With the increase in substrate concentration, the velocity of the enzymatic reaction rise at first. The reaction ultimately reaches a maximum velocity V(max) which is not exceeded by any further rise in concentration of the substrate. This is because the enzyme molecules are fewer than the substrate molecule and after saturation of these molecules, there are no free enzyme molecules to bind with the additional substrate molecule. 2. V(max) |
