Do molecules move from an area of high concentration to an area of 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.

Does diffusion go from low to high concentration or high to low concentration?

Diffusion occurs when the spontaneous net movement of particles or molecules spreads them from an area of high concentration to an area of low concentration through a semipermeable membrane.

What is the type of diffusion when molecules move from areas of high concentration to low concentration without the use of energy?

Simple Diffusion One example of passive transport is diffusion, when molecules move from an area of high concentration (large amount) to an area of low concentration (low amount). Molecules are said to naturally flow down their concentration gradient. This type of diffusion proceeds without an input of energy.

Which type of movement moves from an area of low to an area of high concentration?

Active transport is the movement of dissolved molecules into or out of a cell through the cell membrane, from a region of lower concentration to a region of higher concentration. The particles move against the concentration gradient , using energy released during respiration .

What is the process of diffusion?

diffusion, process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration. A familiar example is the perfume of a flower that quickly permeates the still air of a room.

What is the movement of materials from low to high concentration?

1 Answer. Movement of dissolved molecules from a region of low concentration to region of higher concentration through the cell membrane is called Active Transport.

What is low concentration and high concentration?

High concentration means the amount of solute is high in the solution and low concentration means it is low. Amount of solvent is high in low concentration and low in high concentration of solute.

What is osmosis diffusion?

Osmosis is a specific type of diffusion; it is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration.

Is diffusion high to low?

Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration.

Do molecules move from high to low concentration or low to high concentration in exocytosis?

movement of substances across a plasma membrane that requires energy because the substance is moving against the concentration gradient, from a lower to higher concentration.

What describes the diffusion of molecules?

Diffusion is the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration. The difference in the concentrations of the molecules in the two areas is called the concentration gradient. Diffusion will continue until this gradient has been eliminated.
