Self-phosphorylation is an excellent mechanism for triggering specific catalytic function of the proteins involved in signal cascades because it

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

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

interferes with chemical cascades that trigger contraction of heart muscle

mimics the action of signal receptors

is broken down into hormones that affect the heart

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