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