Answer :
your answer would be active transport now if it was to go from high to low it would be called passive transport
Answer:
Active Transport
Explanation:
In active Transport, a substance moves from a region of low concentration to a region of high concentration by using the energy provided by proteins.
A very known example of active transport in human body is the movement of potassium into the cell and sodium out of the cell by sodium potassium pump which paves the way for movement of sodium and potassium against the concentration gradient.
Thus, it is the active transport process that requires the cell to move particles from low concentration to high concentration.
