Active Transport Involves All of the Following Except The

Question

Active transport involves all of the following except the
A) diffusion of solute through the lipid bilayer of a membrane.
B) pumping of solutes across the membrane.
C) hydrolysis of ATP.
D) transport of solute against a concentration gradient.
E) specific transport protein in the membrane.

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.
