In the following diagram of the lac operon, which is an operon for inducible enzymes , identify the components and enzymes.

Part of enzyme which combines with non-protein part to form fuctional enzymes is

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

Identify the wrong statements (a) The substrate binds to active site of enzyme and not fitting into active site (b) The binding of substrate induces the enzyme to alter its shape (c ) Chemical bonds of substrate break down not to form now enzyme product complex (d) The enzyme releases the products of the reaction and run through catalytic cycle once again
