What effects rate of diffusion?

What is diffusion quizlet. 2) osmosis (diffusion of water) 3) active transport (requires energy/ atp) what are substances such as water, oxygen, carbon dioxide. What is diffusion in chemistry? Diffusion of water across a selectively permeable membrane.

The movement of particles from an area of high concentration to an area of low concentration. Temperature and steepness of concentration gradient, size and surface area. The substance that is being dissolved (salt/sugar) solute.

Does the cell need to expend or utilize energy in order for diffusion to occur? Diffusion is the movement of particles from a high to low particle concentration, while osmosis is the movement of water from a high to a low water concentration.

What is needed for simple diffusion quizlet? Start studying what is diffusion?. Diffusion is the spontaneous mixing of one substance with another when in contact or separated by a permeable membrane.

The movement of people, goods, or ideas across space. Movement of particles or molecules from an area of high concentration to an area of low concentration. Simple passive diffusion occurs when small molecules pass through the lipid bilayer of a cell membrane.
