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 Nitroglycerin has long been administered to human patients suffering from chronic chest pain (angina). This medication works because it interferes with chemical cascades that trigger contraction of heart muscle breaks down into nitric oxide, which increases blood flow to the heart mimics the action of signal receptors is broken down into hormones that affect the heart interferes with chemical cascades that trigger contraction of heart muscle breaks down into nitric oxide, which increases blood flow to the heart mimics the action of signal receptors is broken down into hormones that affect the heart 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 Smooth muscle cells could not be made to relax Nitric oxide would no longer be produced It would be more difficult to increase blood flow and reduce blood pressure All of these Smooth muscle cells could not be made to relax Nitric oxide would no longer be produced It would be more difficult to increase blood flow and reduce blood pressure ANSWER DOWNLOAD EXAMIANS APP
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 block the normal functioning of signal transduction mechanisms They destroy the receptors for key signaling molecules They prevent the production of key signaling molecules They alter the chemical structure of key signaling molecules They block the normal functioning of signal transduction mechanisms They destroy the receptors for key signaling molecules They prevent the production of key signaling molecules ANSWER DOWNLOAD EXAMIANS APP
