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: -The movement of ions or molecules against a concentration gradient with the utilisation of energy is known as active transport.

Detailed explanation-3: -In active transport, the molecules move against the concentration gradient whereas in passive transport, the molecules move along the concentration gradient.

Detailed explanation-4: -Active transport involves molecules moving against a gradient or other form of resistance, such as from an area of lower to higher charge. Active transport is used by cells to accumulate needed molecules such as glucose and amino acids.

Detailed explanation-5: -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.
