BIOMOLECULES AND ENZYMES

Detailed explanation-1: -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-2: -Hemoglobin has a quaternary structure. It consists of two pairs of different proteins, designated the and chains. There are 141 and 146 amino acids in the and chains of hemoglobin, respectively.

Detailed explanation-3: -Tertiary Structure The hemoglobin molecule thus formed is composed of four subunits and thus, is called a tetramer.

Detailed explanation-4: -The silk itself is called a natural protein fiber because it is composed of a pattern of amino acids in a secondary protein structure.
