What is a concentration gradient in a cell?
In biology, a concentration gradient results from the unequal distribution of particles, e.g. ions, between two solutions, i.e. the intracellular fluid (the solution inside the cell) and the extracellular fluid (the solution outside the cell).
What is the concentration gradient of a solution?
The concentration gradient of a solute is the change of concentration per unit distance in a solution. A concentration gradient is generated by diffusion between two regions where the concentration of a substance differs; diffusion proceeds until the concentrations in the two regions become equal.
What is a concentration gradient GCSE?
Concentration Gradient This is how substances are transported into and out of cells. The rate in which substances can move across the cell membrane will depend on the concentration gradient. If there are more particles within a specific volume, those particles are considered 'concentrated'.
What is concentration gradient and why is it important?
Definition. A concentration gradient occurs when a solute is more concentrated in one area than another. A concentration gradient is alleviated through diffusion, though membranes can hinder diffusion and maintain a concentration gradient.
What is a concentration gradient quizlet?
concentration gradient. the gradual difference in the concentration of solutes in a solution between two regions.
What is concentration gradient in active transport?
Concentration gradient. A region of space over which the concentration of a substance changes. ATP. Adenosine triphosphate, the primary energy carrier in living things.
What is the concentration gradient of osmosis?
The osmotic gradient is the difference between two concentration solutions at either side of a semi permeable membrane that distinguishes the different percentage of a specific particle concentration that is dissolved in a solution.
Is concentration gradient the same as diffusion?
1 Answer. Molecules diffuse from areas of high concentration, to areas of low concentration, down a concentration gradient. The concentration gradient therefore represents the concept that, just as a ball rolls down a slope, during diffusion molecules move down the concentration gradient.
What is concentration gradient in psychology?
The concentration gradient is an important process for understanding how particles and ions move in random motion in a solution or gas. It is the process used for particles moving from an area of higher concentration in a solution to an area of lower concentration.
What is the role of a concentration gradient in diffusion?
The concentration gradient therefore represents the concept that, just as a ball rolls down a slope, during diffusion molecules move down the concentration gradient. Higher concentration gradients will result in higher rates of diffusion. As the molecules move the gradient evens out until equilibrium is reached.
