In the phosphoinositide cascade, a calcium channel is activated by: a) the heterotrimeric G protein b) cyclic AMP c) IP3 d) DAG 7. In the cascade, protein kinase c is activated by Ca+2 and protein b) cyclic AMPc) IP3 d) DAG a) the heterotrimeric G 8. WebSecreted NO enters platelets where it activates the enzyme guanylate cyclase, which then stimulates the formation of cGMP (cyclic guanosine mono-phosphate). cGMP then blocks the function of phospholipase C. In the absence of NO, phospholipase C cleaves the membrane phospholipid PIP2, which leads to the production of inositol triphosphate (IP3).
