BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Enzymes bind substrates at key locations in their structure called active sites. They are typically highly specific and only bind certain substrates for certain reactions. Without enzymes, most metabolic reactions would take much longer and would not be fast enough to sustain life.

Detailed explanation-2: -Enzymes are specific because different enzymes have differently shaped active sites. The shape of the active site of an enzyme is complementary to the shape of its specific substrate . This means they are the correct shapes to fit together. Temperature has an effect on enzyme activity.

Detailed explanation-3: -Enzymes are highly specific for the substrate. So they cannot be used for different types of reactions. As lock and key model assumes that a high degree of similarity between the shape of substrate and the geometry of the binding site of the enzyme.

Detailed explanation-4: -Enzymes are highly specific both in binding chiral substrates and in catalyzing their reactions a particular enzyme attacks on a particular substrate (it fits like a key in the lock).
