Cell Signalling and Transduction Which of the following statements about G proteins is false? They bind to and are regulated by guanine nucleotides They are involved in signal cascades They become activated when bound to GDP They must be active before the cell can make needed cAMP They bind to and are regulated by guanine nucleotides They are involved in signal cascades They become activated when bound to GDP They must be active before the cell can make needed cAMP ANSWER DOWNLOAD EXAMIANS APP
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 makes the receptor more likely to capture the signaling, molecule changes the shape and thus the enzymatic activity of the proteins involved allows hydrophilic signaling molecules to cross the plasma membrane None of these makes the receptor more likely to capture the signaling, molecule changes the shape and thus the enzymatic activity of the proteins involved allows hydrophilic signaling molecules to cross the plasma membrane ANSWER DOWNLOAD EXAMIANS APP
