An antiporter also carries two different ions or molecules, but in different directions. All of these transporters can also transport small, uncharged organic molecules like glucose. These three types of carrier proteins are also found in facilitated diffusion, but they do not require ATP to work in that process.

Are antiporters active or passive?

Symporters and antiporters are involved in active transport. Antiporters transport molecules in opposite directions, while symporters transport molecules in the same direction.

Do antiporters require energy?

An antiporter also carries two different ions or molecules, but in different directions. All of these transporters can also transport small, uncharged organic molecules like glucose. These three types of carrier proteins are also found in facilitated diffusion, but they do not require ATP to work in that process.
