What does a difference in concentration in a cell create?
a concentration gradient
What is an example of a concentration gradient?
An example of a concentration gradient is the difference in the concentration of ions inside and outside a cell membrane. This difference creates an electrical potential that drives processes such as ion transport and nerve cell signaling.
Is this correct no energy is required for the movement of water molecules across the cell membrane?
No, energy is required for the movement of water molecules across the cell membrane. This process is known as osmosis, where water moves from an area of low solute concentration to an area of high solute concentration, requiring energy to overcome the concentration gradient.
When the concentration is higher on the outside of the cell it is?
When the concentration is higher on the outside of the cell, it creates a concentration gradient that drives passive transport processes like diffusion and osmosis. This gradient allows molecules or ions to move from an area of higher concentration to an area of lower concentration, resulting in the equalization of concentrations inside and outside the cell.
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
What does a difference in concentration in a cell create?
a concentration gradient
What causes a concentration gradient?
a difference of concentration in and outside of a cell.
What cell process is responsible for concentration gradient?
Diffusion
When there are different amounts of a substance on either side of the cell membrane is a what gradient results?
When there are different amounts of a substance on either side of the cell membrane the gradient result is called the concentration gradient. The permeability of the cell membrane will determine which substances can easily pass through the cell causing a change to the concentration gradient.
What happens when concentration gradient 0?
When the concentration gradient is 0, no flow is allowed to go through the cell wall. To get motion through a membrane, the concentration gradient must be higher than 0.
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.
Which term describes the difference in the concentration of a substance across a cells membrane?
concentration gradient
What is the relationship between the electrochemical gradient and the concentration gradient in cellular transport processes?
The electrochemical gradient is a combination of the electrical gradient and the concentration gradient. It influences the movement of ions across cell membranes during cellular transport processes. The concentration gradient refers to the difference in the concentration of ions or molecules inside and outside the cell, while the electrical gradient refers to the difference in charge across the cell membrane. Together, they determine the direction and rate of ion movement in cellular transport processes.
The transport of a substance across the cell membrane against its concentration gradient is called what?
The transport of a substance across the cell membrane against its concentration gradient is called active transport.
What term describes the difference in the concentration of a substance across a cell membrane?
concentration gradient
What term describes the different in the concentration of a substance across a cell's membrane?
concentration gradient
What is an example of a concentration gradient?
An example of a concentration gradient is the difference in the concentration of ions inside and outside a cell membrane. This difference creates an electrical potential that drives processes such as ion transport and nerve cell signaling.
