Detailed explanation-1: -The energy for active transport comes from cellular respiration. Cellular respiration is the process that all cells use to make energy.

Detailed explanation-2: -Active transport is a process that is required to move molecules against a concentration gradient. The process requires energy. Energy for the process is acquired from the breakdown of glucose using oxygen in aerobic respiration. ATP is produced during respiration and releases the energy for active transport.

Detailed explanation-3: -Active transport is the process of moving molecules across a cellular membrane through the use of cellular energy. The alternative to active transport is passive transport, which uses kinetic energy only to move the molecules.

Detailed explanation-4: -The energy produced during respiration is used in many different ways, some examples of what it is used for are: Working your muscles. Growth and repair of cells. Building larger molecules from smaller ones i.e. proteins from amino acids.
