Question

Why does active transport require's energy?​

Answer 1

Answer:

Active transport: moving against a gradient

To move substances against a concentration or electrochemical gradient, a cell must use energy. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the right concentrations of ions and molecules in living cells
