Question

Name the largest family of cell surface receptor?

(a) GPCR

(b) Ion-channel receptor

(c) Enzyme-linked receptor

(d) Nuclear receptor

This question was addressed to me during an internship interview.

This intriguing question originated from Cell Signaling topic in section Cell Structure and Functions of Life Sciences

Answer 1

Correct answer is (a) GPCR

For explanation I would say: GPCR is a G-protein coupled receptor; it requires G-protein for transmission of signals to the intracellular receptor. It is present in all eukaryotes and it includes receptors which are responsible for smell, light, and taste.
