NEET Chemistry (general) MCQ Question
Type: MCQ-conceptual-Easy-Class 12
Which of the following statements about biomolecules is correct?
A
Starch is the main storage polysaccharide in plants and is composed of a-glucose.
B
Lactose is a polysaccharide composed of b-D-galactose and b-D-glucose.
C
Fructose is a disaccharide found in honey and is a polymer of glucose.
D
Denaturation of proteins occurs without any changes to their primary structure.
Correct Answer
Option A
Detailed Explanation
Starch is indeed the main storage polysaccharide in plants, composed of a-glucose units, as mentioned in the NCERT context. Lactose is a disaccharide, not a polysaccharide, and fructose is a monosaccharide, not a polymer of glucose. Denaturation affects the higher structures of proteins, but not the primary structure.
