• A. Both simple and facilitated diffusion are represented by hyperbolic graphs.
• B. Both simple and facilitated diffusion are represented by linear graphs.
• C. Facilitated diffusion is represented by a linear graph, while simple diffusion is represented by a hyperbolic graph.
• D. Simple diffusion is represented by a linear graph, while facilitated diffusion is represented by a hyperbolic graph.
