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 must be active before the cell can make needed cAMP They become activated when bound to GDP They bind to and are regulated by guanine nucleotides They are involved in signal cascades They must be active before the cell can make needed cAMP They become activated when bound to GDP ANSWER DOWNLOAD EXAMIANS APP
Cell Signalling and Transduction Why is it that inhaling nitric oxide reduces blood pressure only in the lung tissue and not elsewhere in the body*? Because nitric oxide breaks down quickly and thus cannot travel far None of these Because other body tissues use a different signaling molecule Because nitric oxide cannot cross cell membranes and enter the blood Because nitric oxide breaks down quickly and thus cannot travel far None of these Because other body tissues use a different signaling molecule Because nitric oxide cannot cross cell membranes and enter the blood ANSWER DOWNLOAD EXAMIANS APP
