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 mimics the action of signal receptors breaks down into nitric oxide, which increases blood flow to the heart is broken down into hormones that affect the heart interferes with chemical cascades that trigger contraction of heart muscle mimics the action of signal receptors breaks down into nitric oxide, which increases blood flow to the heart 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? 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 All of these Smooth muscle cells could not be made to relax ANSWER DOWNLOAD EXAMIANS APP
