Some membrane channels perform active transport of ca2+ ions into the cell across the membrane with positive potential (0.35v). for each mole of cations, such a channel utilizes hydrolysis of 1 atp molecule. show that this calcium channel will be able to transport ions against 10x concentration gradient.
