NEETBotanyBiomolecules (B)
Read the following statements and choose the correct option: 1. Starch forms helical secondary structures. 2. Cellulose does not contain complex helices. 3. Polysaccharides are long chains of sugars 4. Cellulose is a polymeric polysaccharide consisting of only one type of monosaccharide i.e. glucose
Options
- AAll are correct
- BAll are incorrect except 4
- COnly 1 is incorrect
- DOnly 2 is incorrect
Correct answer
A. All are correct
Step-by-step solution
Starch forms helical secondary structures. In fact, starch can hold I2 molecules in the helical portion. The starch I2 is blue in colour. Cellulose does not contain complex helices and hence cannot hold I2.
