WebDiffusion occurs through the membrane but as the cell size increases the surface area to volume ratio decreases. This means the rate of diffusion slows down, the process of diffusion is useful to cells so if they don’t get nutrients in or waste out fast enough they die. WebFeb 16, 2024 · Mass of Particle: Heavier particles will move more slowly and so will have a slower rate of diffusion. Smaller particles on the other hand will diffuse faster because they can move faster.

WebThe lighter gases pass through the small openings more rapidly (at a higher rate) than the heavier ones (Figure 9.29). In 1832, Thomas Graham studied the rates of effusion of different gases and formulated Graham’s law of effusion: The rate of effusion of a gas is inversely proportional to the square root of the mass of its particles:

WebFeb 16, 2024 · Mass of the molecules: Lighter molecules, such as CH 4 (methane), move more rapidly on average than do more massive ones, such as long segments of nucleic acids (e.g., DNA). Area and thickness of the membrane: As the area of the membrane increases, so does the diffusion rate. But increasing thickness slows diffusion.
