Final answer:

The Na+/Glucose transporter is a symporter, a transport protein that moves two substances in the same direction across a cell membrane.

Step-by-step explanation:

The Na+/Glucose transporter is an example of a symporter, which is a type of carrier protein that transports two different substances in the same direction across the cell membrane.

Specifically, it is known as the Sodium-Glucose Linked Transporter (SGLT), which uses the electrochemical gradient of sodium ions moving into the cell to facilitate the active transport of glucose into the cell against its concentration gradient. This process occurs in kidney cells and in the cells of the small intestine, aiding in glucose absorption and reabsorption, respectively.
