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 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 None of these ANSWER DOWNLOAD EXAMIANS APP
