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 A signal cascade induced by adrenaline or thyroxine All of these 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 involves the activation of a G protein All of these 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 involves the activation of a G protein ANSWER DOWNLOAD EXAMIANS APP
