Cell Signalling and Transduction The binding of ligands to many G-proteins linked receptors leads to shortlived increase in the concentration of certain intracellular signaling molecules called second messenger increase in the concentration of certain extracellular signaling molecules called first messenger decrease in the concentration of certain extracellular signaling molecules called first messenger decrease in the concentration of certain intracellular signaling molecules called second messenger increase in the concentration of certain intracellular signaling molecules called second messenger increase in the concentration of certain extracellular signaling molecules called first messenger decrease in the concentration of certain extracellular signaling molecules called first messenger decrease in the concentration of certain intracellular signaling molecules called second messenger ANSWER DOWNLOAD EXAMIANS APP
