Answer:
The Na⁺/Ca²⁺ exchanger, which couples the movement of Na⁺ down its electrochemical gradient with the movement of Ca²⁺ against its electrochemical gradient, is a(n) <u>symporter secondary active transport </u>because Ca²⁺ and Na⁺ move in different directions across the membrane.
Explanation:
The Na⁺/Ca²⁺ exchanger is a secondary active transport because it uses the energy of the Na⁺ that moves in favor of its electrochemical gradient to bring a Ca²⁺ ion against its electrochemical gradient inside the cell. This transport needs the help of a symporter, which is a protein that moves two different ions in the same direction.
