Question

carbon dioxide (co₂) is created by cells all over the body as a waste product. it is a small nonpolar molecule. carbon dioxide exits cells by moving across cell membranes using a form of passive transport called simple diffusion. this video shows the simple diffusion of carbon dioxide molecules. the diffusion of carbon dioxide is called simple because carbon dioxide can diffuse directly through the phospholipid bilayer without assistance. select the true statements. carbon dioxide only crosses the cell membrane in one direction. diffusion is a form of passive transport. the unassisted diffusion of molecules directly through the phospholipid bilayer is called simple diffusion. carbon dioxide can move across cell membranes via simple diffusion because it is large and polar.

Explanation:

• Diffusion is passive transport. Simple diffusion is unassisted through phospholipid bilayer. CO₂ is small non - polar and diffuses simply.

Answer:

B. Diffusion is a form of passive transport.
C. The unassisted diffusion of molecules directly through the phospholipid bilayer is called simple diffusion.
D. Carbon dioxide can move across cell membranes via simple diffusion.
