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)

the response would be the sodium potassium pump, which, due to the presence of ATP, the polarity of the membrane changes, this pump is activated and makes a counter-gradient exchange with the external medium and the cell, exchanging 3 Na (Sodium) for 2 K (potassium).

Explanation:

Esta bomba es una de las más importantes en la vitalidad celular, debido a que se encargan de mantener el equilibrio osmótico interno de una célula.

secondary active transport

Explanation:

Secondary active transport is a form of active transport across a biological membrane in which a transporter protein couples the movement of an ion typically Na+ or H+ down its electrochemical gradient to the uphill movement of another molecule or ion against a concentration/electrochemical gradient.

Secondary active transport uses the energy stored in these gradients to move other substances against their own gradients.
