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.

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.
What is the difference between diffusion and active transport?
Diffusion is the movement of molecules from areas of high concentration to areas of low concentration and active transport is the movement of molecules from an area of low concentration to an area of high concentration
Differences between diffusion and active transport?
Diffusion is the passive movement of molecules from an area of high concentration to an area of low concentration, while active transport requires energy to move molecules against their concentration gradient, from an area of low concentration to an area of high concentration. Active transport is selective, meaning it can move specific molecules, whereas diffusion is non-selective.
Why is osmosis considered passive?
Osmosis is considered passive because it does not require energy input from the cell to occur. It involves the movement of water molecules across a semipermeable membrane from an area of high concentration to an area of low concentration. This process is driven by the concentration gradient and occurs spontaneously.
What isThe difference in concentration between a region of high concentration and one of lower concentration?
Regarded as existing through Space, or Time, or from one end of an aqueous Solution to the 'other'; these differences are seen to occur across a GRADIENT. In other related circumstances we are talking about a Spectrum.
How do molecules move up a concentration gradient?

This movement can occur through processes such as diffusion or osmosis, where molecules move across a membrane without the need for energy input.
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.
What is the difference between diffusion and active transport?
Diffusion is the movement of molecules from areas of high concentration to areas of low concentration and active transport is the movement of molecules from an area of low concentration to an area of high concentration
How is diffusion determined?
Diffusion is determined by the concentration gradient, temperature, and the size of the molecules. The greater the difference in concentration, the higher the temperature, and the smaller the molecules, the faster diffusion will occur.
Differences between diffusion and active transport?
Diffusion is the passive movement of molecules from an area of high concentration to an area of low concentration, while active transport requires energy to move molecules against their concentration gradient, from an area of low concentration to an area of high concentration. Active transport is selective, meaning it can move specific molecules, whereas diffusion is non-selective.
What is diffusion occurs because of the what movement of molecules?
No, diffusion does not occur because of random molecular movement. It is rather as a result of movement of molecules from areas of high concentration to lower concentration.
Difference between osmosis and diffusion?
Diffusion is the movement of substance (anything- solid ,liquid, gas, etc.) from a higher concentration gradient to a lower concentration gradient.Osmosis is the net movement of water molecules from higher concentration gradient to a lower concentration gradient through a partially permeable membraneSo the difference is that diffusion involves movement of any particles/ substance (e.g. solid, liquid, gas) while osmosis can only occur with water.Another one is that diffusion can occur with or without a membrane but osmosis can only occur with a membrane.Hope this helps. :)
How can diffusion occur in one direction?
Diffusion is the net movement of molecules from the region of higher concentration to region of lower concentration.Explanation:Diffusion is a passive process. It is like when you open a bottle of perfume, soon the whole room will be covered with its smell. From region where the concentration is high, the molecules move to the regions where the concentration is low down the concentration gradient unless equilibrium is reached. Diffusion is the net movement of molecules from the region of higher concentration to region of lower concentration.
Will osmosis occur faster if the concentration of solute is increased?
Yes, osmosis will occur faster when the concentration of solute is increased because there is a steeper concentration gradient driving the movement of water molecules across the semi-permeable membrane. This results in a higher rate of water movement from an area of low solute concentration to an area of high solute concentration.
Would the passive movement of substances occur if the interstitial solute concentration was the same as the filtrate solute concentration?
No, passive movement of substances occurs due to concentration gradients between two areas. If the interstitial solute concentration is the same as the filtrate solute concentration, there would be no concentration gradient to drive passive movement.
Why does active transport require more energy than osmosis or facilitated diffusion?
Active transport requires more energy than diffusion this is because during active transport, the molecules are being transported against and toward the concentration gradient whereas in diffusion, the molecules go from the concentration gradient.
What are the conditions required for osmosis to occur?
The following conditions are required for osmosis to occur: 1) A selectively-permeable membrane 2) Concentration difference
