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 Smooth muscle cells could not be made to relax All of these Nitric oxide would no longer be produced It would be more difficult to increase blood flow and reduce blood pressure Smooth muscle cells could not be made to relax All of these Nitric oxide would no longer be produced ANSWER DOWNLOAD EXAMIANS APP
Cell Signalling and Transduction In paracrine signaling, the signaling molecules affects only target cells close to the cell from which it was secreted both (a) and (b) None of these target cells distant from its site of synthesis in cells of an endocrine organ target cells close to the cell from which it was secreted both (a) and (b) 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 Why is it that inhaling nitric oxide reduces blood pressure only in the lung tissue and not elsewhere in the body*? Because nitric oxide breaks down quickly and thus cannot travel far None of these Because other body tissues use a different signaling molecule Because nitric oxide cannot cross cell membranes and enter the blood Because nitric oxide breaks down quickly and thus cannot travel far None of these Because other body tissues use a different signaling molecule 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 the release of nitric oxide from endothelial cells relaxation of smooth muscle cells reduced blood pressure All of these the release of nitric oxide from endothelial cells relaxation of smooth muscle cells reduced blood pressure All of these ANSWER DOWNLOAD EXAMIANS APP
