When a receptor is overstimulated it becomes . When this occurs the subunit of the G-protein recruits to the membrane, which the receptor. This attracts to the receptor, which binds to its intracellular domains. This blocks its interaction with and targets it for accumulating in -coated pits.

The diagram illustrates the activity of vesicles during a cellular process.

Match the following terms describing electrical events with the correct phases of the cardiac cycle. the ventricular muscle cells depolarize at the start of this phase. during this phase, na+ entry through the funny channels causes the pacemaker potential of sa nodal cells to gradually become less negative until it reaches threshold. the ventricular muscle cells repolarize right before this phase. the cytosolic concentration of calcium in the contractile cells of the ventricle is highest during this phase. a. isovolumetric relaxation b. ventricular ejection c. isovolumetric contraction d. ventricular filling
