In diffusion, substances flow with a concentration gradient, meaning that they flow from areas of high concentration to areas of lower concentration. Flowing against a concentration gradient would be going from an area of low concentration to an area of higher concentration, but this only occurs in active transport.
ll
Diffusion is affected by a decrease in concentration gradient because concentration gradient is directly proportional to the rate of diffusion. A decrease in concentration gradient also lowers the rate of diffusion.
When a region of higher concentration to a region of Lower concentration against the gradient which requires Energy is called Active Transport
The concentration gradient is the difference in the concentration of a substance from one location to another. The plasma membrane controls the traffic .
Concentration Gradient
yes cause the more concentration the quicker
diffusion
Diffusion occurs when there is a concentration gradient i.e. a substance moves from higher to lower concentration.
If a substance moves down its concentration gradient, it means that it is moving from an area where it has a high concentration to an area where it has a low concentration. This is known as diffusion.
Difference in concentration of a substance at 2 areas is called gradient , and it allows diffusion .
Diffusion is affected by a decrease in concentration gradient because concentration gradient is directly proportional to the rate of diffusion. A decrease in concentration gradient also lowers the rate of diffusion.
Osmotic Pressure. It exists anywhere that there is a soluble substance concentration gradient; that is, not only when a membrane separates substance concentrations. See: Brownian Motion.
A difference in the concentration throughout space because diffusion doesn't just happen in a cell or aqueous solution by definition diffusion is just from high to low concentration
When a region of higher concentration to a region of Lower concentration against the gradient which requires Energy is called Active Transport
The larger the concentration gradient (bigger difference between the two solutes across semipermeable membrane) the faster the rate of diffusion.
False
Diffusion is complete when there ceases to be a concentration gradient. For example diffusion has ended if the concentration of a substance is equal on the inside and outside of a permeable membrane, this state is also referred to as dynamic equilibrium.
passive transport Movement down a concentration gradient is known as diffusion.
