What process is the movement of molecules down a concentration gradient until equilibrium is reached?
The movement of molecules down a concentration gradient until equilibrium is reached is called diffusion. This process occurs when molecules naturally move from an area of higher concentration to an area of lower concentration, driven by their kinetic energy. Diffusion continues until the concentration of molecules is uniform throughout the space, achieving equilibrium where there is no net movement of molecules in any direction.
What else can I help you with?
Molecules move in and out freely from high to low concentration?
This process is called simple diffusion, where molecules passively move down their concentration gradient, from an area of high concentration to an area of low concentration, in order to achieve equilibrium. This is a fundamental mechanism for the movement of small non-polar molecules across a cell membrane.
What does the passive in passive transport mean?
Passive Transport is the movement of molecules down a concentration gradient from a region of high concentration to a region of low concentration until equilibrium is reached. Some examples are diffusion and osmosis. Basically, it's a movement of molecules across a membrane that doesn't require energy (ATP)
What is a concentration gradient?
It is the difference in concentration (molecules of a solute per volume of solution) between two locations. Because of the motion of molecules, they are said to diffuse (move, spread) from an area of greater concentration to an area of lesser concentration. Some molecules are always moving in the opposite direction, but the overall trend is "down" the gradient until equilibrium is established between the two regions. And, generally, the larger the gradient or difference, the faster the rate of the diffusion.
How is cancentraion garandiet similer to diffusion?
Both concentration gradient and diffusion involve the movement of particles from an area of high concentration to an area of low concentration. In concentration gradient, the difference in concentration drives the movement of particles, while in diffusion, the random movement of particles leads to their spread across a concentration gradient. Both processes aim to reach equilibrium by balancing the distribution of particles.
What is the movement of sucrose molecules called?
The movement of sucrose molecules is called diffusion, which is the process of molecules spreading out from an area of high concentration to an area of low concentration. This movement occurs until equilibrium is reached.
How can molecules move against the concentration gradient and reach equilibrium?
Molecules can move against the concentration gradient through active transport, which requires energy input. This process allows molecules to be transported from an area of lower concentration to an area of higher concentration, ultimately reaching equilibrium through the continuous movement of molecules.
Does active transport involve the movement of molecules against the concentration gradient?
Yes, active transport involves the movement of molecules against the concentration gradient.
How do molecules move up a concentration gradient?
Molecules move up a concentration gradient through a process called passive transport. This involves the movement of molecules from an area of low concentration to an area of high concentration, driven by the natural tendency of molecules to spread out and reach equilibrium. This movement can occur through processes such as diffusion or osmosis, where molecules move across a membrane without the need for energy input.
Diffusion continues until there is no?
Diffusion continues until there is no longer a concentration gradient present between the two regions. Once equilibrium is reached, the molecules will be evenly distributed throughout the system and diffusion will stop.
What does it mean when you are going with the concentration gradient?
Going with the concentration gradient is basically the process of diffusion. Molecules going from a low concentration to a high concentration would be going with the concentration gradient. Going against the concentration gradient would be the movement of particles from a high concentration to a low concentration
Is the movement of molecules across a membrane down the concentration gradient a passive or active process?
The movement of molecules across a membrane down the concentration gradient is a passive process.
How long does movement occur across a concentration gradient?
Movement across a concentration gradient occurs until equilibrium is reached, where the concentration of a substance is the same on both sides of the gradient. The rate of movement depends on factors such as the size of the gradient, temperature, and properties of the substance.
Diffusion is the process of movement of molecules under a concentration gradient?
Yes
Compare osmosis diffusion and filtration?
Osmosis is the movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration. Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration until equilibrium is reached. Filtration involves the movement of particles through a barrier, typically driven by a pressure gradient, with the goal of separating substances based on size.
How does the movement of molecules occur down a concentration gradient?
The movement of molecules down a concentration gradient happens through a process called diffusion. This is when molecules move from an area of high concentration to an area of low concentration, driven by the natural tendency of particles to spread out evenly. This movement continues until the concentration is balanced throughout the system.
Molecules move in and out freely from high to low concentration?

This is a fundamental mechanism for the movement of small non-polar molecules across a cell membrane.
