Cell Signalling and Transduction In paracrine signaling, the signaling molecules affects only target cells close to the cell from which it was secreted target cells distant from its site of synthesis in cells of an endocrine organ both (a) and (b) None of these target cells close to the cell from which it was secreted target cells distant from its site of synthesis in cells of an endocrine organ both (a) and (b) None of these ANSWER DOWNLOAD EXAMIANS APP
Cell Signalling and Transduction Why is it that inhaling nitric oxide reduces blood pressure only in the lung tissue and not elsewhere in the body*? Because other body tissues use a different signaling molecule None of these Because nitric oxide breaks down quickly and thus cannot travel far Because nitric oxide cannot cross cell membranes and enter the blood Because other body tissues use a different signaling molecule None of these Because nitric oxide breaks down quickly and thus cannot travel far Because nitric oxide cannot cross cell membranes and enter the blood ANSWER DOWNLOAD EXAMIANS APP
Cell Signalling and Transduction In vasodilation, proper nerve signals sent to blood vessels cause All of these relaxation of smooth muscle cells the release of nitric oxide from endothelial cells reduced blood pressure All of these relaxation of smooth muscle cells the release of nitric oxide from endothelial cells reduced blood pressure ANSWER DOWNLOAD EXAMIANS APP
Cell Signalling and Transduction The signaling molecules called steroid hormones bind to cell surface receptors to trigger chemical cascades are hydrophilic and so cannot penetrate the plasma membrane are made in one location of the body but have their effects some distance away never enter the blood of humans bind to cell surface receptors to trigger chemical cascades are hydrophilic and so cannot penetrate the plasma membrane are made in one location of the body but have their effects some distance away never enter the blood of humans ANSWER DOWNLOAD EXAMIANS APP
Cell Signalling and Transduction What is the name of the protein signaling molecule that alters glucose uptake, and where would its receptors be located? NGF; the nerves involved in simple reflexes Insulin; beta cells of the pancreas Insulin; many different cell types that use glucose for fuel PDGF; the blood NGF; the nerves involved in simple reflexes Insulin; beta cells of the pancreas Insulin; many different cell types that use glucose for fuel PDGF; the blood ANSWER DOWNLOAD EXAMIANS APP
