Diffusion Many things will impact how much and how quickly a substance will diffuse across a membrane. Use this gizmo to investigate the factors that affect diffusion. How do Membrane Permeability and Temperature Affect Diffusion?

What Does Membrane Permeability And Temperature Have to Do with Diffusion?

The membrane’s permeability, temperature and other factors play an important role in the diffusion process of molecules. Diffusion refers to the movement of molecules from one area with a higher concentration to another. Temperature and membrane permeability are two factors that will determine the speed and extent of diffusion of a substance across a membrane. Brown (2016). Membrane permeability refers to how quickly molecules can move through the membrane. The membrane’s permeability is how quickly molecules can pass through it. This will be faster than if the membrane has lower permeability. The reason for this is that membranes of high permeability are more porous and have wider openings, which allow molecules to flow through the membrane faster. Low permeability membranes will make it more difficult for molecules to pass through and slow down diffusion. The temperature also plays a significant role in the speed of diffusion. As temperature rises, diffusion rates also increase. The reason for this is that molecules move faster and more efficiently when temperatures rise. This allows them to pass the membrane quicker (Brown 2016, Brown). However, as the molecules move more, diffusion rates will fall if temperature drops. Cont…
