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 All of these reduced blood pressure the release of nitric oxide from endothelial cells relaxation of smooth muscle cells All of these reduced blood pressure ANSWER DOWNLOAD EXAMIANS APP
Cell Signalling and Transduction Self-phosphorylation is an excellent mechanism for triggering specific catalytic function of the proteins involved in signal cascades because it changes the shape and thus the enzymatic activity of the proteins involved allows hydrophilic signaling molecules to cross the plasma membrane makes the receptor more likely to capture the signaling, molecule None of these changes the shape and thus the enzymatic activity of the proteins involved allows hydrophilic signaling molecules to cross the plasma membrane makes the receptor more likely to capture the signaling, molecule None of these 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? 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 NGF; the nerves involved in simple reflexes Insulin; beta cells of the pancreas Insulin; many different cell types that use glucose for fuel ANSWER DOWNLOAD EXAMIANS APP
Cell Signalling and Transduction Cell signaling can be classified into None of these three distinct types based on the distance over which the signaling molecules act three distinct types based on the signaling molecules two distinct types based on the distance over which the signaling molecules act None of these three distinct types based on the distance over which the signaling molecules act three distinct types based on the signaling molecules two distinct types based on the distance over which the signaling molecules act 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 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 ANSWER DOWNLOAD EXAMIANS APP
