Q. Arrange the steps of catalytic action of an enzyme in order and choose the correct option. The enzyme releases the products of the reaction and the enzyme is free for another substrate. The active site of enzyme is in close proximity of the substrate and breaks of chemical bonds of the substrate. The binding of substrate induces the enzyme to alter its shape fitting more tightly around the substrate. The substrate binds to the active site of the enzyme fitting into the active site.
