The process used by the liver cell is called active transport
Active transport is the process by which substances move across a cell membrane from an area of low concentration to an area of high concentration. In active transport, molecules move against the concentration gradient and the process need cellular energy to perform the movement.
The process used by the liver cell to move vitamins from an area of low concentration, across the cell membrane, to an area of high concentration is called as active transport.
Further Explanation:
Diffusion is the movement of solute particles from a region of higher concentration to a region of lower concentration. The movement of solutes is based on concentration or electrical gradient which is collectively called as electrochemical gradient. Passive transport requires no energy as it occurs down the electrochemical gradient. Active transport takes place against the electrochemical gradient and it requires energy to transport solutes.
There are two types of active transport based on the type of energy used to transport solutes across the cell membrane. Primary active transport involves hydrolysis of ATP (Adenosine triphosphate) to provide energy for the movement of solutes. Secondary active transport involves coupling of movement of two different solutes that is movement of one solute down its electrochemical gradient drives the movement of other solute against its normall gradient.
