Question

All members of the nuclear receptor family:

A. Do not undergo conformational changes.

B. are cell-surface receptors

C. Interact with signal molecules that diffuse through the plasma membrane.

D. are found only in the cytoplasm

Answer 1

Question:-

Answer:- The correct answer is c) Interact with signal molecules that diffuse through the plasma membrane.

Explanation:- Nuclear receptors are a family of receptors that interact with different ligands and produce signals.

Nuclear receptors are found in the cytoplasm as well as in the nucleus adjacent to the nuclear material. For acting on these receptors, different signalling molecules diffuse through the plasma membrane of the cell amd produce response.

Other options:-

• They do undergo confirmational changes after binding to the signalling molecules.
• They are not cell surface receptors.
• They are present in nucleus along with their distribution to the cytoplasm.
