Question

Quizplus · Accepted Answer

Secondary active transport is the transport process that uses the energy stored in a Na+ or H+ concentration gradient to drive other substances across the membrane against their own concentration gradients. This type of transport requires the energy from the primary active transport of sodium or hydrogen ions.
