from an area of high concentration to an area of lower concentration.
This is called diffusion. Substances move randomly, from an area of high concentration to an area of low concentration. Osmosis is a specific type of diffusion that only involves the random movement of water.
The movement of a substance from an area of high concentration to an area of low concentration is known as diffusion. This process occurs due to the random motion of particles, leading to a net movement of particles down their concentration gradient. Diffusion is driven by the principle of entropy, seeking to achieve a state of equilibrium where the concentration of the substance is uniform throughout the system.
If a substance is passing out of a cell by diffusion, it suggests that the concentration of the substance is higher inside the cell than outside. This movement is driven by the substance's tendency to move from an area of higher concentration to an area of lower concentration to reach equilibrium.
Yes, movement of a substance down its concentration gradient is considered passive transport because it does not require energy expenditure by the cell. The substance moves from an area of high concentration to an area of low concentration through processes like simple diffusion, facilitated diffusion, or osmosis.
Active transport or facilitated diffusion could result in the net movement of a substance into a cell if it is more concentrated inside the cell than in the surroundings. In active transport, energy is required to move the substance against its concentration gradient. In facilitated diffusion, specific carrier proteins help the substance move into the cell down its concentration gradient.
