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). The other type of proteins (fibrous proteins) have long thin structures and are found in tissues like muscle and hair.

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. Acetylcholinesterase: These enzymes break down the neurotransmitter acetylcholine in nerves and muscles. Helicase: Helicase enzymes unravel DNA.

Detailed explanation-4: -All enzymes are proteins, but all proteins are not enzymes.

Detailed explanation-5: -Carbohydrase breaks down carbohydrates into sugars. Lipase breaks down fats into fatty acids. Protease breaks down protein into amino acids. 12-May-2021
