g protiens recptors part 2 0.0 / 5 ? Biologycell physiologyUniversityNone Created by: anna888Created on: 27-10-22 17:39 Gs protien receptor vs Gi protien receptor alpha subunits in each? Gs has alpha s subunit- stimulate AC. Gi has alpha i subunits - inhibits AC 1 of 11 exaple of gs and gi protien? Gs- beta-adrenorecptor. Gi - alpha 2 adrenoreceptor 2 of 11 describe Gq protien receptor and action of subunits contains alphaq11 subunits and activates PLC 3 of 11 decribe role of PLC action on membrane and cleaves PIP2 into IP3 and DAG 4 of 11 decribe IP3 and its action hydrophillic,travels to ER and releases Ca+2 ions. also promotes influx of Ca+2 from outside cell. Ca+2 influx causes cell response 5 of 11 describe DAG features and roles hydrophobic,remains on membrane and reruits PKC and phosphorilates it , this inreases effect of IP3 6 of 11 describe Ca+2 role binds to protien CaM, which activates CaMK involved in smooth muscle contraction 7 of 11 example of Gq reptor alpha 1 adrenorecptor 8 of 11 describe vasoconstriction in terms of cell signal pathway, include receptor example alpha 1 adrenoreptor, Gq-PLC-IP3-Ca+2-CaM-CaMK pathway for muscle contraction,bp increases 9 of 11 describe vasodilation in terms of cell signal pathway, include receptor example beta 2 adrenoreceptor via Gs-cAMP-PKA pathway. PKA phospholiates protien which causes bp to decrease 10 of 11 how many types of metatrophic receptors are there? what class are each 5.M-1,3,5 are Gq stimulatory(ACh activated). M-2,4 are Gi 11 of 11
