Cell Signalling and Transduction The signaling molecules called steroid hormones are made in one location of the body but have their effects some distance away never enter the blood of humans are hydrophilic and so cannot penetrate the plasma membrane bind to cell surface receptors to trigger chemical cascades are made in one location of the body but have their effects some distance away never enter the blood of humans are hydrophilic and so cannot penetrate the plasma membrane bind to cell surface receptors to trigger chemical cascades 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 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
Cell Signalling and Transduction A cell is known to respond to a particular signaling molecule. Which of the following must be true of this cell? It is incapable of signal transduction It is in the heart muscle It is also the site of production for the signaling molecule It contains the receptor for the signaling molecule It is incapable of signal transduction It is in the heart muscle It is also the site of production for the signaling molecule It contains the receptor for the signaling molecule ANSWER DOWNLOAD EXAMIANS APP
