BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Among the organic macromolecules, enzymes belong in the category of proteins. Proteins are distinct from carbohydrates, nucleic acids, and lipids in that a protein is made of amino acids.

Detailed explanation-2: -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. This, in turn, determines the three-dimensional structure of the enzyme, including the shape of the active site.

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.

Detailed explanation-4: -An enzyme is an organic molecule (usually a protein) that catalyzes a cellular reaction.

Detailed explanation-5: -A protein is an organic molecule composed of amino acids linked by peptide bonds.
