Carbon dioxide exits cells by simple diffusion between phospholipid molecules in the plasma membrane.

Question

Quizplus · Accepted Answer

Carbon dioxide is a small and lipid-soluble molecule that can easily pass through the plasma membrane by simple diffusion, moving from an area of high concentration to an area of low concentration until equilibrium is reached. Therefore, it exits cells by diffusion between phospholipid molecules in the plasma membrane.
