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*? None of these Because nitric oxide cannot cross cell membranes and enter the blood Because other body tissues use a different signaling molecule Because nitric oxide breaks down quickly and thus cannot travel far None of these Because nitric oxide cannot cross cell membranes and enter the blood Because other body tissues use a different signaling molecule Because nitric oxide breaks down quickly and thus cannot travel far ANSWER DOWNLOAD EXAMIANS APP
