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.
What different solutions can cells be in and what happenes to them?
There are three different types of solutions you can place a cell in: hypotonic (concentration of solution less than concentration of cell), isotonic (equal concentrations) and hypertonic (concentration of solution greater than concentration of cell). In a hypotonic solution, the cell will accumulate water (in an attempt to equalize the concentration difference) and will eventually rupture from the water pressure inside the cell. In an isotonic solution, the cell will do nothing. In a hypertonic solution, the cell will shrivel as the water exits the cell to dilute the solution to the same concentration as the cell. This will cause the cell to die.
What condition in cells versus their environments causes water to move through cell membranes?
The difference in solute concentration between cells and their environments, also known as osmotic gradient, causes water to move through cell membranes. Water molecules move from an area of lower solute concentration to an area of higher solute concentration in an attempt to equalize the concentration on both sides of the membrane.
Which term describes The difference InThe concentrations of A Substance Across a cell's Membrane?
The term that describes the difference in concentrations of a substance across a cell's membrane is called a concentration gradient. It refers to the variation in the concentration of molecules or ions between two regions, leading to the movement of substances down their concentration gradient through processes like diffusion or active transport.
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 causes a concentration gradient?
a difference of concentration in and outside of a cell.
What does a difference in concentration create?
Gradient
What is the difference in chloride concentration inside and outside the cell?
The chloride concentration is higher outside the cell than inside the cell.

concentration gradient

Define When a cell use energy to move material across cell membrane?
if it is against a concentration difference.
As the concentration of molecules outside a cell increases more molecules will enter the cell?
Yes, this process is known as osmosis. Water moves from an area of low solute concentration (outside the cell) to an area of high solute concentration (inside the cell) to balance the concentration levels. This causes more molecules to enter the cell as the concentration difference increases.
Why is water hypotonic?
Water is hypotonic because it has a lower concentration of solutes compared to the inside of a cell. This difference in solute concentration causes water to move into the cell, which can lead to swelling and potentially bursting of the cell.
What term describes the difference in the concentrations of a substance across a cell membrane?
concentration gradient
What term describes the difference in concentrations of a substance across a cell's membrane?
concentration gradient
Why does oxygen always diffuse into an animal cell?
Oxygen diffuses into animal cells because of a concentration gradient. Oxygen is higher in concentration in the external environment or surrounding tissues compared to inside the cell. This difference in concentration drives the passive diffusion of oxygen into the cell to maintain balance.
Is resting potential caused by a difference in the concentration of certain ions inside and outside the cell?
True
