After it has been activated a G-protein _______.

		moves along the inside of the cell's membrane and activates enzymes
		binds to its receptor in the cell's nucleus and initiates translation

Expert Solution

Step 1

G protein or guanine nucleotide-binding proteins are part of the G protein-coupled receptor (GPCR) or seven-transmembrane receptor, which helps in various cell signaling processes. There are two types of G proteins – small G protein and heterotrimeric G protein complexes. The heterotrimeric G protein consists of α, β, and γ subunits.
