Cell Signalling and Transduction Which of the following is true about a hydrophilic signaling molecule? It is a steroid Its receptor is located in the cytosol of the target cell It might trigger a signal cascade that causes some effect in a cell Since it can enter the cell, it directly affects some specific cell process It is a steroid Its receptor is located in the cytosol of the target cell It might trigger a signal cascade that causes some effect in a cell Since it can enter the cell, it directly affects some specific cell process 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? Smooth muscle cells could not be made to relax All of these It would be more difficult to increase blood flow and reduce blood pressure Nitric oxide would no longer be produced Smooth muscle cells could not be made to relax All of these It would be more difficult to increase blood flow and reduce blood pressure Nitric oxide would no longer be produced ANSWER DOWNLOAD EXAMIANS APP
