Cell Signalling and Transduction Which of the following is true about a hydrophilic signaling molecule? Since it can enter the cell, it directly affects some specific cell process Its receptor is located in the cytosol of the target cell It might trigger a signal cascade that causes some effect in a cell It is a steroid Since it can enter the cell, it directly affects some specific cell process Its receptor is located in the cytosol of the target cell It might trigger a signal cascade that causes some effect in a cell It is a steroid ANSWER DOWNLOAD EXAMIANS APP
Cell Signalling and Transduction A signal cascade induced by adrenaline or thyroxine involves the activation of a G protein must begin with receipt of the signal molecule by a surface receptor results in the activation of a sequence of enzymes needed for the cell effect All of these involves the activation of a G protein must begin with receipt of the signal molecule by a surface receptor results in the activation of a sequence of enzymes needed for the cell effect All of these ANSWER DOWNLOAD EXAMIANS APP
Cell Signalling and Transduction In the signal transduction mechanism known as protein phosphorylation All of these the signaling molecule binds to a surface receptor phosphorylated proteins act with enzymes to trigger the signal cascade receptor kinases play a key role in triggering the signal cascade All of these the signaling molecule binds to a surface receptor phosphorylated proteins act with enzymes to trigger the signal cascade receptor kinases play a key role in triggering the signal cascade ANSWER DOWNLOAD EXAMIANS APP
Cell Signalling and Transduction Nitroglycerin has long been administered to human patients suffering from chronic chest pain (angina). This medication works because it is broken down into hormones that affect the heart interferes with chemical cascades that trigger contraction of heart muscle mimics the action of signal receptors breaks down into nitric oxide, which increases blood flow to the heart is broken down into hormones that affect the heart interferes with chemical cascades that trigger contraction of heart muscle mimics the action of signal receptors breaks down into nitric oxide, which increases blood flow to the heart ANSWER DOWNLOAD EXAMIANS APP
