| Which is true about Biopolymers? |
| 1. They are produced by living organisms and contain monomeric units that are covalently bonded to form larger structures. |
| 2. Cellulose is the most common organic compound and biopolymer on Earth. |
| 3. Many biopolymers spontaneously fold into characteristic compact shapes, which determine their biological functions and depend in a complicated way on their primary structures. |
| 4. Biopolymers are also called renewable polymers. |
| 5. The major drawbacks with biopolymer is that it cannot be sustainable. |
| 6. Biopolymers are biodegradable, and some are also compostable. Select the correct answer using the codes given below |
A) 1, 2, 4 and 6
B) 2, 3, 4, 5 and 6
C) 1, 2, 3, 4 and 6
D) 2, 5 and 6
Correct Answer: C
Solution :
[c] Biopolymers are polymers produced by living organisms; in other words, they are polymeric biomolecules. Since they are polymers, biopolymers contain monomeric units that are covalently bonded to form larger structures. There are three main classes of biopolymers, classified according to the monomeric units used and the structure of the biopolymer formed: polynucleotides (RNA and DNA), which are long polymers composed of 13 or more nucleotide monomers polypeptides, which are short polymers of amino acids; and polysaccharides, which are often linear bonded polymeric carbohydrate structures.
