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.
What else can I help you with?
When the concentration of a substance differs from one area to another this is called concentration?
This is called a concentration gradient, which represents the difference in concentration of a substance between two locations. The substance will naturally move down the concentration gradient from areas of higher concentration to lower concentration through processes like diffusion or active transport.
The difference in concentration of a substance across space is called a?
The difference in concentration of a substance across space is called a concentration gradient. This gradient drives the movement of molecules from regions of higher concentration to regions of lower concentration through processes like diffusion or active transport.
What is the difference in the concentration of a substance across a space is called concentration?
The difference in concentration of a substance across a space is called a concentration gradient. It represents the change in concentration over a given distance and drives processes like diffusion and osmosis. Substances move from areas of high concentration to areas of low concentration along the concentration gradient to achieve equilibrium.
Why is diffusion affected by a decrease in concentrated gradient?
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.
What does concentration gradient have to do with diffusion of substances across the cell membrane?
The concentration gradient refers to the difference in concentration of a substance between two regions. In the context of cell membranes, substances tend to move from areas of higher concentration to areas of lower concentration to reach equilibrium. This movement is known as diffusion and it is driven by the concentration gradient.
Movement of a substance down the substance's concentration gradient?
diffusion
Where and when does diffusion occur?
Diffusion occurs when there is a concentration gradient i.e. a substance moves from higher to lower concentration.
What does it means if a substance moves down its concentration gradient?
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.
When the concentration of a substance differs from one area to another this is called concentration?
This is called a concentration gradient, which represents the difference in concentration of a substance between two locations. The substance will naturally move down the concentration gradient from areas of higher concentration to lower concentration through processes like diffusion or active transport.
What is meant by the term gradient?
Difference in concentration of a substance at 2 areas is called gradient , and it allows diffusion .
The difference in concentration of a substance across space is called a?
The difference in concentration of a substance across space is called a concentration gradient. This gradient drives the movement of molecules from regions of higher concentration to regions of lower concentration through processes like diffusion or active transport.
How does the Concentration gradient of a substance affect the movement of that substance and the expenditure of energy?
A concentration gradient of a substance drives the movement of that substance from an area of high concentration to an area of low concentration. The steeper the concentration gradient, the faster the movement of the substance, requiring less energy to transport it. If the concentration on both sides of the gradient is equal, there is no net movement of the substance.
What is necessary for simple diffusion?
For simple diffusion to occur, a concentration gradient must exist where a substance moves from an area of higher concentration to an area of lower concentration. Additionally, the cell membrane must be permeable to the substance diffusing, allowing it to pass through freely.
What is the difference in the concentration of a substance across a space is called concentration?
The difference in concentration of a substance across a space is called a concentration gradient. It represents the change in concentration over a given distance and drives processes like diffusion and osmosis. Substances move from areas of high concentration to areas of low concentration along the concentration gradient to achieve equilibrium.
What is the pressure for diffusion that is produced by the concentration gradient?
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.
If diffusion is going to occur there has to be what?
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
Why is diffusion affected by a decrease in concentrated gradient?
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.
