Cell Signalling and Transduction The signaling molecules called steroid hormones never enter the blood of humans bind to cell surface receptors to trigger chemical cascades are made in one location of the body but have their effects some distance away are hydrophilic and so cannot penetrate the plasma membrane never enter the blood of humans bind to cell surface receptors to trigger chemical cascades are made in one location of the body but have their effects some distance away are hydrophilic and so cannot penetrate the plasma membrane 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 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 None of these ANSWER DOWNLOAD EXAMIANS APP
