Answer 1

A plot of V0 vs [S] yields a hyperbolic curve that plateaus as it approaches Vmax due to the fact that the active site is saturated with substrate​​​​​​. When all the active sites of enzyme molecules are occupied by substrate, the velocity of the reaction could not be increased further by adding more substrate because all the active sites are blocked by subtract molecules.
