Multiple Choice

Which of the following statements correctly describes the difference between facilitated diffusion and simple diffusion in the context of acids and bases?

Facilitated diffusion requires a protein carrier, while simple diffusion does not.

Facilitated diffusion occurs only in acidic environments, while simple diffusion occurs in basic environments.

Facilitated diffusion is faster than simple diffusion due to the presence of acids.

Facilitated diffusion involves the movement of bases, while simple diffusion involves the movement of acids.

Verified step by step guidance

Understand the concept of diffusion: Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration. It can occur with or without the assistance of proteins.

Define simple diffusion: Simple diffusion is the passive movement of molecules directly through the lipid bilayer of the cell membrane without the need for any protein carriers. It is driven by the concentration gradient.

Define facilitated diffusion: Facilitated diffusion is also a passive transport process, but it requires the presence of specific protein carriers or channels in the cell membrane to help transport molecules across the membrane.

Compare the two processes: The key difference between facilitated diffusion and simple diffusion is the requirement of protein carriers in facilitated diffusion. Simple diffusion does not require these proteins.

Apply the concepts to acids and bases: In the context of acids and bases, facilitated diffusion would involve the use of protein carriers to transport these molecules, whereas simple diffusion would allow them to pass directly through the membrane without assistance.
