Imposing a transmembrane potential positive with respect to the medium on chromaffin granule ghosts increased the initial rate of the delta pH-induced uptake of noradrenaline, whereas imposing a negative potential decreased this rate. The increase of the uptake rate was proportional to the potential. The ATP-induced uptake of noradrenaline was also sensitive to the potential since imposing a transient negative potential onto the positive potential generated by the membrane ATPase induced a latency in this transport.
相对于介质在嗜铬粒蛋白颗粒膜泡上施加一个正的跨膜电位，会增加δpH诱导的去甲肾上腺素摄取的初始速率，而施加一个负电位则会降低该速率。摄取速率的增加与电位成正比。ATP诱导的去甲肾上腺素摄取也对电位敏感，因为在膜ATP酶产生的正电位上施加一个短暂的负电位会在这种转运中诱导一个延迟。
