What process is characterized by the movement of particles from an area of high concentration to an area of low concentration across the plasma membrane without the use of energy?

What process is characterized by the movement of particles from an area of high concentration to an area of low concentration across the plasma membrane without the use of energy?

The passive transport is a process which is characterized by the movement of particles from an area of high concentration to an area of low concentration across the plasma membrane without the use of energy because, its particle move by themselves due to entropy.

What is the process by which particles move from an area of high concentration to an area of low concentration?

Diffusion is the movement of a substance from an area of high concentration to an area of low concentration. Diffusion happens in liquids and gases because their particles move randomly from place to place. Diffusion is an important process for living things; it is how substances move in and out of cells.

What is it called when a substance moves from an area of high concentration to an area of low concentration until the concentration is equal across the space?

Diffusion is a passive process of transport (see Figure 2). A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across a space. You are familiar with diffusion of substances through the air.

What is the relationship between diffusion rate and equilibrium?

Since diffusion moves materials from an area of higher concentration to the lower, it is described as moving solutes “down the concentration gradient.” The end result of diffusion is an equal concentration, or equilibrium, of molecules on both sides of the membrane. At equilibrium, movement of molecules does not stop.

What is the meaning of high concentration and low concentration?

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

Why does water move from low to high solute concentration?

“In osmosis, water moves from areas of low concentration of solute to areas of high concentration of solute.” So osmosis only occurs with a semipermeable membrane, and even with the membrane some water will move both sides. MORE water will move up the concentration gradient, thus there is a net flow up the gradient.
