E) specific transport protein in the membrane.

Question

Quizplus · Accepted Answer

Active transport does not involve the diffusion of solute through the lipid bilayer of a membrane. Instead, it requires the use of energy to move solutes against a concentration gradient or to pump them across the membrane with the help of specific transport proteins. Hydrolysis of ATP provides the energy needed for active transport.
