A scientist is observing a membrane through which water and some small hydrophobic molecules can freely pass along a concentration gradient from high to low.However,some sugar molecules are too large to pass through the membrane either way without the assistance of passive transport proteins.Additionally,small Na⁺ ions and some proteins can pass through the membrane against the concentration gradient,but both require the assistance of active transport proteins.What general type of membrane are they observing?
