What is meant by (i) peptide linkage (ii) biocatalysts?
(i) Peptide linkage: a peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O). This is a dehydration synthesis reaction (also known as a condensation reaction) and usually, occurs between amino acid. Peptide linkage is responsible for the primary structure of protein.

(ii) Biocatalysis is catalysis in living (biological) systems in which natural catalysts, such as protein enzymes, perform chemical transformations on organic compounds. For example DNA polymerization by DNA polymerase or Joining of DNA by DNA ligases.
