Cell Signalling and Transduction Self-phosphorylation is an excellent mechanism for triggering specific catalytic function of the proteins involved in signal cascades because it None of these changes the shape and thus the enzymatic activity of the proteins involved allows hydrophilic signaling molecules to cross the plasma membrane makes the receptor more likely to capture the signaling, molecule None of these changes the shape and thus the enzymatic activity of the proteins involved allows hydrophilic signaling molecules to cross the plasma membrane makes the receptor more likely to capture the signaling, molecule 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 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 None of these Because nitric oxide cannot cross cell membranes and enter the blood Because nitric oxide breaks down quickly and thus cannot travel far Because other body tissues use a different signaling molecule None of these Because nitric oxide cannot cross cell membranes and enter the blood Because nitric oxide breaks down quickly and thus cannot travel far ANSWER DOWNLOAD EXAMIANS APP
