Question

Quizplus · Accepted Answer

A selectively permeable membrane is designed to only allow certain molecules to pass through it. This type of membrane is essential in a variety of biological processes, as it helps to regulate what goes in and out of cells and organelles. In contrast, a permeable membrane allows all molecules to pass through, while a porous membrane has large holes that allow anything to pass through. Countertransport is a specific type of protein-mediated transport that involves moving two different molecules in opposite directions across a membrane.
