Cell Signalling and Transduction In vasodilation, proper nerve signals sent to blood vessels cause relaxation of smooth muscle cells 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 ANSWER DOWNLOAD EXAMIANS APP
Cell Signalling and Transduction The hormone or ligand can be considered as second messenger none of these first messenger both (a) and (b) second messenger none of these first messenger both (a) and (b) 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 cannot cross cell membranes and enter the blood None of these Because nitric oxide breaks down quickly and thus cannot travel far Because other body tissues use a different signaling molecule Because nitric oxide cannot cross cell membranes and enter the blood None of these 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 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? All of these Nitric oxide would no longer be produced Smooth muscle cells could not be made to relax It would be more difficult to increase blood flow and reduce blood pressure All of these Nitric oxide would no longer be produced Smooth muscle cells could not be made to relax It would be more difficult to increase blood flow and reduce blood pressure ANSWER DOWNLOAD EXAMIANS APP
Cell Signalling and Transduction In the signal transduction mechanism known as protein phosphorylation receptor kinases play a key role in triggering the signal cascade All of these the signaling molecule binds to a surface receptor phosphorylated proteins act with enzymes to trigger the signal cascade receptor kinases play a key role in triggering the signal cascade All of these the signaling molecule binds to a surface receptor phosphorylated proteins act with enzymes to trigger the signal cascade ANSWER DOWNLOAD EXAMIANS APP
