B) 7-transmembrane segment (7-TMS) receptors
C) cell adhesion protein receptors
D) single-transmembrane segment catalytic receptors
E) none of the above

Question

Quizplus · Accepted Answer

G-proteins are associated with the 7-transmembrane segment (7-TMS) receptor superfamily, which includes receptors for various signaling molecules such as neurotransmitters, hormones, and cytokines. These receptors are characterized by their seven transmembrane domains and the ability to activate G-proteins upon ligand binding, leading to downstream signaling cascades.
