Cell Signalling and Transduction Self-phosphorylation is an excellent mechanism for triggering specific catalytic function of the proteins involved in signal cascades because it allows hydrophilic signaling molecules to cross the plasma membrane None of these changes the shape and thus the enzymatic activity of the proteins involved makes the receptor more likely to capture the signaling, molecule allows hydrophilic signaling molecules to cross the plasma membrane None of these 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 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 ANSWER DOWNLOAD EXAMIANS APP
