What transport process couples the movement of an ion against its electrochemical gradient to another ion that is moving down its electrochemical gradient that was established using cellular energy (ATP)?

Question

Quizplus · Accepted Answer

Secondary active transport involves the movement of an ion against its electrochemical gradient, which is coupled to the movement of another ion moving down its gradient. This process indirectly uses energy stored in the gradient of the second ion, which was originally established by primary active transport using ATP.
