Idenfity the false statement about G-protein coupled receptors
α - subunit gets seperated from β, γ subunits after binding to GTP, not GDP.
G-Protein coupled receptors have 7 transmembrane segments and 3 subunits
α subunit carries inherent GTPase activity
α subunit seperates from β, γ subunit after binding to GDP
α(s) stimulates adenylyl cyclase and ↑ cAMP
