The phospholipid bilayer of membranes is highly permeable to small non-polar molecules such as dissolved carbon dioxide. Which of the following is most likely to affect the rate of its diffusion?

Question

Quizplus · Accepted Answer

The rate of diffusion of carbon dioxide (a small non-polar molecule) across a phospholipid bilayer is primarily affected by the concentration gradient, as diffusion is a passive process that moves molecules from an area of higher concentration to an area of lower concentration without the need for energy input.
