NEET BIOLOGY

Detailed explanation-1: -Enzymes are protein macromolecules. Proteins are large biopolymer molecules that are made up of repeating monomer units called amino acids.

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: -Proteins are functional macromolecules responsible for catalysing the biochemical reactions that sustain life.

Detailed explanation-4: -Definition. An enzyme is a biological catalyst and is almost always a protein. It speeds up the rate of a specific chemical reaction in the cell.
