NEET Chemistry Proteins MCQ Question
Which of the following statements about proteins and their structures is correct?
Globular proteins are typically soluble in water and exhibit a spherical shape.
The primary structure of a protein is determined by its quaternary structure.
All naturally occurring amino acids are optically active due to their symmetric structure.
Proteins can only consist of a single polypeptide chain without any complex structure.
Correct Answer
Detailed Explanation
Globular proteins, as mentioned in the NCERT context, are characterized by their spherical shape and solubility in water, with examples like insulin and albumins. The primary structure is the specific sequence of amino acids, distinct from the more complex quaternary structure, and not all amino acids are optically active.
