SECTION E – MEMBRANES AND CELL SIGNALING E3  Membrane transport:  small molecules

ATP-driven active In the case of ATP-driven active transport, the energy transport required for the transport of the molecule (Na+, K+, Ca2+ or H+) (primary active across the membrane is derived from the coupled hydrolysis transport) of ATP (e.g. Na+/K+-ATPase), an example of a P-type ATPase.
