The Michaelis constant K_(m) is

Define Michaelis constant (km) of an enzyme.

Michaelis Menten Constant (K_(m)) is equal to

Assertion : With the increase in substrate concentration, the velocity of the enzymatic reaction rise at first. The reaction ultimately reaches a maximum velocity which is not exceeded by any further rise in concentration of the substrate. Reason : The enzyme molecules are fewer than substrate molecules and after saturation of thes molecules, there are no free enzymes to bind with the additional substrate molecules.

An enzyme [E] is combined with the substrate [S] as follows: E+S underset(K_(-1))overset(K_(1))hArr ES ES overset(K_(2))rarr P +E The overall reaction rate is given by: Rate =(V_("max")[S])/(K_(m)+[S]) and the rate of reaction varies with substrate concentration as: The order of reaction at point A is :

Substrate concentation at which an enzyme attains half its maximum velocity is
