Cell Signalling and Transduction The signaling molecules called steroid hormones 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 never enter the blood of humans 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
