What is the movement of a substance from one place to another?
Diffusion is the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration. This is due to the random movement of the molecules. The difference in the concentration of a substance between two areas is called the concentration gradient .
What is the movement of substances from an area of higher concentration to an area of lower concentration?
Diffusion. Diffusion is a process of passive transport in which molecules move from an area of higher concentration to one of lower concentration.
What is the movement of large substances?
ENDOCYTOSIS AND EXOCYTOSIS: MOVEMENT OF LARGE PARTICLES It is possible for large molecules to enter a cell by a process called endocytosis, where a small piece of the cell membrane wraps around the particle and is brought into the cell. If the particle is solid, endocytosis is also called phagocytosis.
What is the movement of a substance out of a cell called?
The movement of substances in and out of the cell by diffusion is known as passive transport. However, sometimes substances will not diffuse across the membrane and need to be chemically assisted. This is known as active transport.
When a substance move from an area of low concentration to an area of high concentration while using energy the process is termed?
During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP).
Is the movement of substances from a region of high concentration to a region of low concentration?
Diffusion is the net movement of substances from an area of higher concentration to an area of lower concentration. This movement occurs as a result of the random and constant motion characteristic of all molecules, atoms, or ions (due to kinetic energy) and is independent from the motion of other molecules.
How does the movement of substances take?
Diffusion is a passive process of transport. 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. Materials move within the cell ‘s cytosol by diffusion, and certain materials move through the plasma membrane by diffusion.
