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

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

makes the receptor more likely to capture the signaling, molecule

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

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

mimics the action of signal receptors

Its receptor is located in the cytosol of the target cell

It is a steroid

It might trigger a signal cascade that causes some effect in a cell

Since it can enter the cell, it directly affects some specific cell process
