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 is broken down into hormones that affect the heart mimics the action of signal receptors breaks down into nitric oxide, which increases blood flow to the heart interferes with chemical cascades that trigger contraction of heart muscle is broken down into hormones that affect the heart mimics the action of signal receptors breaks down into nitric oxide, which increases blood flow to the heart ANSWER DOWNLOAD EXAMIANS APP

Cell Signalling and Transduction Why is it that inhaling nitric oxide reduces blood pressure only in the lung tissue and not elsewhere in the body*? Because other body tissues use a different signaling molecule Because nitric oxide cannot cross cell membranes and enter the blood None of these Because nitric oxide breaks down quickly and thus cannot travel far Because other body tissues use a different signaling molecule Because nitric oxide cannot cross cell membranes and enter the blood None of these Because nitric oxide breaks down quickly and thus cannot travel far ANSWER DOWNLOAD EXAMIANS APP
