BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Answer and Explanation: Enzymes are protein macromolecules. Proteins are large biopolymer molecules that are made up of repeating monomer units called amino acids. There are 20 different common amino acids that make up proteins like enzymes.

Detailed explanation-2: -Macromolecules are basically polymers, long chains of molecular sub-units called monomers. Carbohydrates, proteins and nucleic acids are found as long polymers. Due to their polymeric nature and large size, they are known as macromolecules.

Detailed explanation-3: -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-4: -Enzymes are not carbohydrates. They are mostly proteins, although there are some nucleic acids (ribozymes) that act as enzymes. Various factors like pH, temperature, the concentration of enzymes and substrates, and the presence of activators influence the rate of enzymatic reactions.
