BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Specificity is a property of the enzyme and describes how restrictive the enzyme is in its choice of substrate; a completely specific enzyme would have only one substrate.

Detailed explanation-2: -Since the substrate must fit into the active site of the enzyme before catalysis can occur, only properly designed molecules can serve as substrates for a specific enzyme; in many cases, an enzyme will react with only one naturally occurring molecule.

Detailed explanation-3: -Enzymes only work with specific substrates because each substrate has a unique 3 dimensional shape. For enzymes to catalyze a reaction they need to bind the substrate and then they need to interact with the substrate in the active site.

Detailed explanation-4: -Enzymes are highly specific in action. Almost every biochemical reaction is controlled by its own specific enzymes. Thus, the enzyme urease catalyzes the hydrolysis of urea. No other enzyme catalyzes this reaction.
