Arrange the steps of catalytic action of an enzyme in order and choose the correct option.

(I) The enzyme releases the products of the reaction and gets free for another substrate.

(II)The active site of enzyme is in close proximity of the substrate and breaks chemical bonds of the substrate.

(III) The binding of substrate induces the enzyme to alter its shape, fitting more tightly around the substrate.

(IV) The substrate binds to the active sites of the enzyme, fitting into the active sites.
