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 allows hydrophilic signaling molecules to cross the plasma membrane changes the shape and thus the enzymatic activity of the proteins involved makes the receptor more likely to capture the signaling, molecule None of these allows hydrophilic signaling molecules to cross the plasma membrane changes the shape and thus the enzymatic activity of the proteins involved makes the receptor more likely to capture the signaling, molecule 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*? 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 Because other body tissues use a different signaling molecule Because nitric oxide cannot cross cell membranes and enter the blood ANSWER DOWNLOAD EXAMIANS APP
