Cell Signalling and Transduction In terms of cell communication, what do bacterial pathogens such as cholera and anthrax have in common? They alter the chemical structure of key signaling molecules They destroy the receptors for key signaling molecules They prevent the production of key signaling molecules They block the normal functioning of signal transduction mechanisms They alter the chemical structure of key signaling molecules They destroy the receptors for key signaling molecules They prevent the production of key signaling molecules They block the normal functioning of signal transduction mechanisms ANSWER DOWNLOAD EXAMIANS APP

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 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 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? It would be more difficult to increase blood flow and reduce blood pressure Smooth muscle cells could not be made to relax Nitric oxide would no longer be produced All of these It would be more difficult to increase blood flow and reduce blood pressure Smooth muscle cells could not be made to relax Nitric oxide would no longer be produced All of these ANSWER DOWNLOAD EXAMIANS APP
