What is the term for the movement of molecules from an area of lower concentration to an area of higher concentration?
If it is the movement of molecules then it is diffusion. If it the movement of water then it is osmosis
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.
Why is there a diffusion gradient in the tissues?
A diffusion gradient exists in tissues due to differences in concentration of substances. This gradient drives the passive movement of molecules from areas of higher concentration to areas of lower concentration, allowing cells to obtain necessary nutrients and get rid of waste products.
What requires no energy to move molecules across a membrane?
Passive transport, such as diffusion, osmosis, and facilitated diffusion, does not require energy to move molecules across a membrane. These processes rely on the concentration gradient to drive the movement of molecules from an area of higher concentration to an area of lower concentration.
What is The process by which small molecules pass through a membrane by moving from an area of high concentration to an area of low concentration is?
This process is called passive diffusion or simple diffusion. It does not require energy input and relies on the concentration gradient to drive the movement of molecules across the membrane.
Diffusion is the process of movement of molecules under a concentration gradient?
Yes
COMPARE osmosis and diffusion?
Diffusion is movement of molecules, from region of higher concentration, to the region of lower concentration, along concentration gradient.
What is diffusion in science terms?
In biology, diffusion is the passive movement of molecules or particles along a concentration gradient, or from regions of higher to regions of lower concentration. Diffusion is the free movement of particles in a liquid or gas down a concentration gradient.
Is diffusion quicker when there is a higher concentration gradient?
Yes, diffusion is quicker when there is a higher concentration gradient because it drives the movement of molecules from areas of higher concentration to areas of lower concentration more rapidly. The steeper the concentration gradient, the faster the rate of diffusion.

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 is the random movement of molecules and ions down their concentration gradient called?
The random movement of molecules and ions down their concentration gradient (meaning from an area of high concentration to an area of low concentration) is called simple diffusion. Simple diffusion is related to the magnitude of driving force, permeability of the membrane, and surface area.
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.
Why is there a diffusion gradient in the tissues?
A diffusion gradient exists in tissues due to differences in concentration of substances. This gradient drives the passive movement of molecules from areas of higher concentration to areas of lower concentration, allowing cells to obtain necessary nutrients and get rid of waste products.
Diffusion is the movement of molecules from?
Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.
Compare and contrast active transport and facilitated diffusion-?
Active transport requires energy input to move molecules against their concentration gradient, while facilitated diffusion does not require energy and relies on carrier proteins to move molecules down their concentration gradient. Both processes involve the use of proteins to transport molecules across the cell membrane, but active transport can move molecules against their concentration gradient, while facilitated diffusion can only move molecules down their concentration gradient.
How do molecules travel in passive transport when moving up their concentration gradient?
In passive transport, molecules move up their concentration gradient without using energy. This process relies on the natural movement of molecules from areas of high concentration to areas of low concentration. This movement is driven by the principle of diffusion, where molecules spread out to achieve a balance.
