Web18 dec. 2016 · The answer is active transport! For example, consider the enzyme that creates ATP – ATP synthase. ATP synthase relies on a gradient of hydrogen ions to operate and create new ATP molecules. ATP synthase is essentially extracting energy from this hydrogen ion gradient by allowing the facilitated diffusion of hydrogen ions. WebActive transport is an active process that requires energy in the form of ATP, while diffusion is a passive process that does not require any energy. Active transport … batman tfs
