Solution Diffusion :Diffusion is the net movement of molecules from an area of higher concentration to an area of lower concentration. The difference in the concentration of a substance between two areas is called the concentration gradient.Diffusion occurs in liquids and gases when their particles collide randomly and spread out. Final answer: Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration.Passive transport process Passive transport describes the movement of substances down a concentration gradient and does not require energy consumption.
Active transport processes Active transport is the movement of solutes against a gradient and requires the expenditure of energy (usually ATP). Active transport is achieved through one of the following two mechanisms:
What is the movement of molecules from high to low concentration?Diffusion is the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration. For cell transport, diffusion is the movement of small molecules across the cell membrane.
