WebConnection for AP ® Courses. If a substance must move into the cell against its concentration gradient, the cell must use free energy, often provided by ATP, and carrier proteins acting as pumps to move the substance. Substances that move across membranes by this mechanism, a process called active transport, include ions, such as Na + and K +. WebThe electrical gradient is a consequence of the charge separation across the membrane (when the protons H + move without a counterion, such as chloride Cl −). In most cases the proton-motive force is generated by an … WebThe permeability for the counter-ions under the driving force of an electrical potential gradient should be high to minimise the membrane IR losses. 2.
