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: -This statement is false. Active transport and passive transport both require the use of transport proteins to move a substrate into or out of a cell. The difference between the two processes is whether or not energy is required.
Detailed explanation-4: -Movement Across a Membrane and Energy Passive mechanisms like diffusion use no energy, while active transport requires energy to get done.
