Cell Signalling and Transduction Which of the following is true about a hydrophilic signaling molecule? It is a steroid Since it can enter the cell, it directly affects some specific cell process It might trigger a signal cascade that causes some effect in a cell Its receptor is located in the cytosol of the target cell It is a steroid Since it can enter the cell, it directly affects some specific cell process It might trigger a signal cascade that causes some effect in a cell Its receptor is located in the cytosol of the target cell 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? 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 All of these ANSWER DOWNLOAD EXAMIANS APP
