Natural rubber is a protein as it's main constituent{monomer}IS ISOPRENE.While for synthetic rubber it is neoprene.
Hope it was helpful!

Long chain of monomer.

What I know its a polymer not a protein because protein is made up of amino acid.

Pink said:   1 decade ago
Cellulose&starch are made up of amino acids.

So I think natural rubber is correct.

Soumit said:   1 decade ago
Cellulose and starch are not made up of amino acids. Proteins are, therefore starch or cellulose can't be protein and none of the other cannot be the answer. So the answer would automatically be [A] natural rubber.

Protein is a huge structure containing more than 100 peptide (amide) bonds and all the 20 essential and non essential amino acids few of which are glycine, alanine, valine, leucine, isoleucine, etc. I think N.O.T.

Its obviously none of above.

Abhishek said:   10 years ago
Structural unit of the protein is amino acids so answer is none of these.

Siri said:   9 years ago
How the answer should be a natural rubber?

Kiran said:   9 years ago
Yes, none of the above is the answer.
