What is a Diffusion?
Movement of molecules of a substance from its higher concentration towards its lower concentration by their own kinetic energy is called diffusion.
What is the most important factor in explaining why diffusion occurs spontaneously?
the process of diffusion is when molecules of any substance spread out into available space. because diffusion always occurs moving from an area of high concentration to low concentration it is said to be moving down its concentration gradient and therefore no work must be done to move the substance. Because no work is being done, diffusion decreases free energy therefore making it a spontaneous process.
Is diffusion an active mechanism?
False
What is facilitated diffusion across the phospholipid membrane?
Facilitated diffusion is the movement a substance from high concentration to low concentration across a membrane through a transporter protein or channel
What is the net movement of substances to regions of lower concentration called?
This process is called diffusion. If the substance moving is water, it is called osmosis.
What is The net movement of particles of a substance from a high concentration to a low concentration?
DIFFUSION DIFFUSION
Movement of a substance down the substance's concentration gradient?
diffusion
The movement of a substance across a concentration difference is called?
diffusion
How are osmosis and diffusion different?
Diffusion is the net movement of a substance through a membrane from a higher concentration to a lower concentration. Osmosis is the diffusion of water.
What is the movement of a substance from an area of great concentration to an area of lesser concentration?
Molecular Diffusion
What is a Diffusion?
Movement of molecules of a substance from its higher concentration towards its lower concentration by their own kinetic energy is called diffusion.
Is the movement of a substance to an area of low concentration from an area of high concentration?
passive transport Movement down a concentration gradient is known as diffusion.
What is the movement a substance to an area of low concentration from an area of high concentration?
passive transport Movement down a concentration gradient is known as diffusion.
Compare and contrast the processes of osmosis and diffusion?
Diffusion and filtration are two examples of passive transport. Between cell membranes. There is no chemical energy required. Diffusion mores from an area of high concentration to a lower concentration, while filtration moves particles of a particular diameter through a membrane.
The mixing and spreading of particles in gases and liquids is called diffusion?
Yes. Diffusion is the movement of particles from where they are in high concentration to where they are in low concentration.
What is the most important factor in explaining why diffusion occurs spontaneously?
the process of diffusion is when molecules of any substance spread out into available space. because diffusion always occurs moving from an area of high concentration to low concentration it is said to be moving down its concentration gradient and therefore no work must be done to move the substance. Because no work is being done, diffusion decreases free energy therefore making it a spontaneous process.
What motion is the next movement of particles of a substance from areas of high concentration to areas of low concentration?
diffusion
