BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Enzymes are proteins comprised of amino acids linked together in one or more polypeptide chains. This sequence of amino acids in a polypeptide chain is called the primary structure.

Detailed explanation-2: -Enzymes are mainly globular proteins-protein molecules where the tertiary structure has given the molecule a generally rounded, ball shape (although perhaps a very squashed ball in some cases).

Detailed explanation-3: -Trypsin: These enzymes break proteins down into amino acids in the small intestine. Lactase: Lactase breaks lactose, the sugar in milk, into glucose and galactose.

Detailed explanation-4: -Enzymes contain a globular protein part called apoenzyme and a non-protein part named cofactor or prosthetic group or metal-ion-activator.
