Question

Cell surface receptors are integral membrane proteins and possess regions that contribute to which of the basic domains?

• A. Extracellular domains
• B. Transmembrane domain
• C. Intracellular domain
• D. All of the above

Answer 1

The correct option is D All of the above

The cell receptors are the molecules which are involved in the transmission of the information from the outside to the inside of the cell and vice versa. These molecules are composed of three domains. The extracellular domain, the transmembrane domain and the intracellular domain are the three parts of the cell receptors.

Thus, the correct answer is option D.
