Question

Which homeostatic process moves particles against a concentration gradient

Answer 1

Answer: Active transport is the correct answer.

Explanation:

Active transport is the homeostatic process which moves particles against a concentration gradient with the use of energy. Active transport is a physiological transport that uses energy, in the form of ATP, to move molecules from an area of low concentration to an area of high concentration. Example of active transport is sodium-potassium pump, which moves sodium ions to the outside of the cell and potassium ions to the inside of the cell.
