C) specific channels
D) all of these

Question

Quizplus · Accepted Answer

Nonpolar molecules, such as gases and small lipids, can diffuse across the membrane's phospholipid bilayer without the requirement of energy or specific transport proteins. Active transport, on the other hand, requires energy input, and specific channels are usually selective and allow only certain molecules to pass through.
