Q. If curve X in the graph (below) represents no inhibition for the reaction of the enzyme with its substrates, the curve representing the competitive inhibition, of the same reaction is

An inducer is absent in the type of enzyme

The kinetic effect of purely competitive inhibitor of an enzyme

A sigmoidal plot of substrate concentration ([S]) verses reaction velocity (V) may indicate

The Km of the enzyme giving the kinetic data as below is

From the Lineweaver-Burk plot of Michaelis-Menten equation, Km and Vmax can be determined when V is the reaction velocity at substrate concentration S, the X-axis experimental data are expressed as

The enzyme which can add water to a carbon-carbon double bond or remove water to create a double bond without breaking the bond is

Fischer’s ‘lock and key’ model of the enzyme action implies that

Activation or inactivation of certain key regulatory enzymes is accomplished by covalent modification of the amino acid

An example of ligases is
