Active transport has two types: primary, which directly uses metabolic energy (like ATP hydrolysis), and secondary, which uses the energy from an existing electrochemical gradient to move another molecule.
Active transport can be categorized into primary active transport, which directly uses metabolic energy, and secondary active transport, which involves coupling a molecule's movement against its gradient with another molecule moving down its electrochemical gradient.
