Answer 1

A protein is a sequence of amino acids. The end of the polypeptide chain of -NH₂ end and at -COOH end are respectively called N - terminal and C - terminal.

Explanation:

In polypeptide chain end with NH₂ is called N-terminal and the other ends with -COOH is called C-terminal. Each amino acid also has an amino group at one end and a carboxyl group and the other so it is an amino acid.
