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*? None of these Because nitric oxide cannot cross cell membranes and enter the blood Because nitric oxide breaks down quickly and thus cannot travel far Because other body tissues use a different signaling molecule None of these Because nitric oxide cannot cross cell membranes and enter the blood Because nitric oxide breaks down quickly and thus cannot travel far Because other body tissues use a different signaling molecule ANSWER DOWNLOAD EXAMIANS APP

Cell Signalling and Transduction In paracrine signaling, the signaling molecules affects only both (a) and (b) target cells close to the cell from which it was secreted None of these target cells distant from its site of synthesis in cells of an endocrine organ both (a) and (b) target cells close to the cell from which it was secreted None of these target cells distant from its site of synthesis in cells of an endocrine organ ANSWER DOWNLOAD EXAMIANS APP
Cell Signalling and Transduction In vasodilation, proper nerve signals sent to blood vessels cause reduced blood pressure the release of nitric oxide from endothelial cells All of these relaxation of smooth muscle cells reduced blood pressure the release of nitric oxide from endothelial cells All of these relaxation of smooth muscle cells ANSWER DOWNLOAD EXAMIANS APP
Cell Signalling and Transduction The signaling molecules called steroid hormones never enter the blood of humans are hydrophilic and so cannot penetrate the plasma membrane bind to cell surface receptors to trigger chemical cascades are made in one location of the body but have their effects some distance away never enter the blood of humans are hydrophilic and so cannot penetrate the plasma membrane bind to cell surface receptors to trigger chemical cascades are made in one location of the body but have their effects some distance away ANSWER DOWNLOAD EXAMIANS APP
Cell Signalling and Transduction If a disease of the blood vessels caused the endothelial cells of the vessel to die, what effect would that have on the cellular activities associated with vasodilation? It would be more difficult to increase blood flow and reduce blood pressure All of these Smooth muscle cells could not be made to relax Nitric oxide would no longer be produced It would be more difficult to increase blood flow and reduce blood pressure All of these Smooth muscle cells could not be made to relax Nitric oxide would no longer be produced ANSWER DOWNLOAD EXAMIANS APP
