Explanation:
Detailed explanation-1: -GPCRs are membrane-bound proteins that have seven membrane-spanning domains connected by intracellular and extracellular domains.
Detailed explanation-2: -Seven-transmembrane (7TM) receptors form the largest superfamily of cell-surface receptors. They respond to a wide range of stimulants including light, hormones, neurotransmitters, and odorants.
Detailed explanation-3: -The 7 transmembrane receptors (7TMRs) also known as G-protein coupled receptors (GPCRs) constitute the largest family of plasma membrane receptors. The superfamily of 7TMRs includes receptors for hormones, neurotransmitters and ion channels, and is critical to mediate physiological and cellular processes [1, 2].
