With active transport, ATP energy is used in the phosphorylation-dephosphorylation cycle of the carrier.

Question

Quizplus · Accepted Answer

Active transport involves the movement of ions or molecules against their concentration gradient, and this process requires energy in the form of ATP. The carrier proteins involved in active transport use ATP energy in the phosphorylation-dephosphorylation cycle to alter their conformation and enable the transport of molecules across the membrane.
