Detailed explanation-1: -Active transport requires energy for the process by transporting molecules against a concentration or electrochemical gradient.

Detailed explanation-2: -During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.

Detailed explanation-3: -The type of transport that moves material against the concentration gradient with the use of energy is called active transport. That energy that it uses is usually in the form of adenosine triphosphate (ATP).

Detailed explanation-4: -Active transport requires energy for the movement of molecules whereas passive transport does not require energy for the movement of molecules. In active transport, the molecules move against the concentration gradient whereas in passive transport, the molecules move along the concentration gradient.

Detailed explanation-5: -There are three main active transport methods-ion pumps, exocytosis and endocytosis.
