A substance that unrelated to substrate reversibly changes the activity of an enzyme. It is

Arrange the steps of catalytic action of an enzyme in order an choose the right option (A) The enzyme releases the products of the reaction and the enzyme is free to bind to another substrate (B) The active site of enzyme is in close proximity of the substrate and breaks the chemical bonds of the substrate (C) The binding of substrate induces the enzyme to alter its shape fitting more tightly around the substrate (D) The substrate binds to the active site of the enzyme fitting into the active site

The steps in catalytic cycle of an enzyme action are given in random order (i) The enzyme releases the products. Now enzyme is free to bind another substrate (ii) The active sites, now in close proximity of substrate breaks the bond of substrate and E-P complex forms (iii) Binding of substrate induces the enzyme to alter its shape fitting more tightly around the substrate (iv) The substrate binds to the active site of enzyme (i.e., fitting into the active site.) The correct order is
