The transport of a substance across the cell membrane against its concentration gradient is called active transport.
Osmosis works with the concentration gradient, meaning that it involves the movement of water molecules from an area of low solute concentration to an area of high solute concentration in order to equalize the solute concentration on both sides of the membrane.
The process of moving materials against a concentration gradient is called active transport. Active transport generally uses a protein pump to move molecules from an area of low concentration to an area of high concentration; in order to perform an active transport, the cell must use some of its energy to initiate the reaction.
active transport
Active transport is the process that requires cellular energy to move a substance against its concentration gradient. This process uses ATP to pump molecules across the cell membrane, creating a concentration gradient where the molecule is more concentrated on one side of the membrane than the other.
