The following statements are the steps in the catalytic action of an enzyme. Arrange them in correct sequence. a) The active site of the enzyme, now in close proximity of the substrate, breaks the chemical bonds of the substrate and the new enzyme product complex is formed. b) The substrate binds tightly to the enzyme, inducing a change in the active site of the enzyme. c) The enzyme releases the products of the reac

Options

  1. Ac, a, b, d
  2. Bd, b, a, c

Correct answer

B. d, b, a, c

Step-by-step solution

The catalytic cycle of an enzyme action can be described in the following steps: First, the substrate binds to the active site of the enzyme, fitting into the active site (Statement d). The binding of the substrate induces the enzyme to alter its shape, fitting more tightly around the substrate (Statement b). The active site of the enzyme, now in close proximity of the substrate, breaks the chemical bonds of the substrate and the new enzyme-product complex is formed (Statement a). The enzyme releases the products o
