Secondary active transport involves moving molecules against their concentration gradient with the help of other molecules. The SGLT2 carrier protein is an example that transports Na+ and glucose. The Na+/K+ ATPase pump plays a crucial role in maintaining ion levels.

Explanation:

Secondary active transport involves the movement of molecules against their concentration gradient with the help of another molecule moving along its gradient. An example is the SGLT2 carrier protein that transports Na+ with its gradient and glucose against its gradient. This transport relies on the Na+/K+ ATPase pump to maintain low intracellular Na+ levels.
