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

changes the shape and thus the enzymatic activity of the proteins involved

makes the receptor more likely to capture the signaling, molecule

allows hydrophilic signaling molecules to cross the plasma membrane

Why is it that inhaling nitric oxide reduces blood pressure only in the lung tissue and not elsewhere in the body*?

Because nitric oxide cannot cross cell membranes and enter the blood

Because other body tissues use a different signaling molecule

Because nitric oxide breaks down quickly and thus cannot travel far

None of these

Nitroglycerin has long been administered to human patients suffering from chronic chest pain (angina). This medication works because it

mimics the action of signal receptors

breaks down into nitric oxide, which increases blood flow to the heart

is broken down into hormones that affect the heart

interferes with chemical cascades that trigger contraction of heart muscle
