Which of the Following Statements Regarding Structural Complementarity is Correct

Question

Which of the following statements regarding structural complementarity is correct?
A)It produces strong irreversible interactions.
B)It is the interaction of a biological macromolecule and its ligand.
C)It is the basis of a select few biological functions.
D)It is the means of ceasing bimolecular interactions.

Accepted Answer

Structural complementarity refers to the match between the shape and chemical properties of a biological macromolecule and its ligand, leading to reversible and specific interactions. Therefore, option B, which describes the interaction between a biological macromolecule and its ligand, is the correct statement. Option A is incorrect because structural complementarity often results in weak interactions, and option C is incorrect because it is responsible for many biological functions. Option D is incorrect because it does not relate to the concept of structural complementarity.
