Question

both symport and antiport require transport proteins. true or false

Explanation:

Symport and antiport are types of cotransport (secondary active transport). Both processes involve the movement of two or more substances across a cell membrane, and they require transport proteins (specifically cotransporters) to facilitate the movement. Symport moves substances in the same direction, while antiport moves them in opposite directions, but both rely on transport proteins.

Answer:

True
