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 other body tissues use a different signaling molecule None of these Because nitric oxide cannot cross cell membranes and enter the blood Because nitric oxide breaks down quickly and thus cannot travel far Because other body tissues use a different signaling molecule None of these Because nitric oxide cannot cross cell membranes and enter the blood Because nitric oxide breaks down quickly and thus cannot travel far 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 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 None of these makes the receptor more likely to capture the signaling, molecule ANSWER DOWNLOAD EXAMIANS APP
Cell Signalling and Transduction Small charged molecules, often biogenic amines function as hormones neurotransmitters none of these both (a) and (b) hormones neurotransmitters none of these both (a) and (b) ANSWER DOWNLOAD EXAMIANS APP
Cell Signalling and Transduction A signal cascade induced by adrenaline or thyroxine involves the activation of a G protein must begin with receipt of the signal molecule by a surface receptor results in the activation of a sequence of enzymes needed for the cell effect All of these involves the activation of a G protein must begin with receipt of the signal molecule by a surface receptor results in the activation of a sequence of enzymes needed for the cell effect All of these ANSWER DOWNLOAD EXAMIANS APP
