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