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