A liver cell requires energy to move vitamins from an area of low concentration, across the cell membrane, to an area of high concentration. The process used by the liver cell is called A) osmosis. B) active transport. C) passive transport. D) facilitated diffusion.

Answers

The correct answer is Active transport.

The transportation of molecules against the concentration gradient from the area of its low concentration to high concentration is called Active Transport.The molecular size of vitamins are large so,  it is not easy to transport them against the concentration gradient without the help of energy. This energy is in the form of ATP.

Thus, liver uses Active Transport to move vitamins from one area to another area.
Alright it is going from a low concentration to a higher concentration.... ACTIVE TRANSPORT is correct . :)
