Cell Signalling and Transduction Which of the following is true about a hydrophilic signaling molecule? Its receptor is located in the cytosol of the target cell Since it can enter the cell, it directly affects some specific cell process It is a steroid It might trigger a signal cascade that causes some effect in a cell Its receptor is located in the cytosol of the target cell Since it can enter the cell, it directly affects some specific cell process It is a steroid It might trigger a signal cascade that causes some effect in a cell ANSWER DOWNLOAD EXAMIANS APP

Cell Signalling and Transduction A signal cascade induced by adrenaline or thyroxine All of these involves the activation of a G protein results in the activation of a sequence of enzymes needed for the cell effect must begin with receipt of the signal molecule by a surface receptor All of these involves the activation of a G protein results in the activation of a sequence of enzymes needed for the cell effect must begin with receipt of the signal molecule by a surface receptor 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 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 Because nitric oxide breaks down quickly and thus cannot travel far ANSWER DOWNLOAD EXAMIANS APP
