The substrate concentration at which the chemical reaction catalyzed by an enzyme attains half of its maximum velocity is termed as

A particle is executing S.H.M. with amplitude 'A' and maximum velocity V_(m) . The displacement at which its velocity is half of the maximum velocity is

Among the statement given below, which statements /s is / are correct regarding the relationship between enzyme and substrate ? I. Above a certain concentration of substrate , an enzyme reaches its maximum rate of reaction II. Increasing the substrate concentration to a higher level doesn't reverse the effects of a competitive inhibitor. III At high substrate concentration , a non competitive inhibitor no longer affects the enzyme activity . IV. The higher the concentration of substrate the faster an enzyme can cataylse a reaction.

The amplitude of a particle performing SHM is 'a'. The displacement at which its velocity will be half the maximum velocity is

Figure given below shows three velocity-substrate concentration curves for an enzyme reaxtion. What do the curves for an enzyme reaction. What do the curves depict

the time after which the particle attains maximum height is :

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.

Enzymes are substrate (the molecule on which an enzyme acts) specific. Give the reason.

The substrate for restriction enzyme is-
