it is called a concentration gradient.
Concentration Gradient
The transport of a substance across the cell membrane against its concentration gradient is called active transport.
it is called osmosis and it is the net movement of water particles across a semi-permable membrane against the concentration gradient!

Active transport is a process that removes substances from a cell against the concentration gradient. The molecules move from low concentration to high concentration during this process.
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.
concentration gradient
Diffusion is the movement of particles from an area of high concentration to an area of lower concentration. Active transport is the movement of substances from lower to higher concentration across a semi permeable membrane that must have a specific protein carrier and cell expenditure of energy.
Various pumps use ATP to move substances across membranes. The pumps are often moving substance from a lower concentration to a higher. This movement is called "against the gradient" as movement usually moves from a higher concentration to a lower to even out the concentration. It takes energy to keep this. The pumps are mostly proteins.
