Detailed explanation-1: -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-2: -Active transport requires energy for the process by transporting molecules against a concentration or electrochemical gradient.
Detailed explanation-3: -What is Active Transport? “Active Transport is defined as a process that involves the movement of molecules from a region of lower concentration to a region of higher concentration against a gradient or an obstacle with the use of external energy.”
Detailed explanation-4: -The process of moving substances against a concentration gradient using ATP is known as active transport. A protein pump uses stored energy in the form of ATP to move molecules during the active transport process. Active transport is of two types such as primary active transport and secondary active transport.
