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.

Respuesta :

Active transport involved all of the following except A. This would simply be simple and or passive diffusion, the movement of solute through a lipid bilayer of a membrane.

Active transport occurs when a solute molecule moves across a membrane against a concentration gradient, this process doesn't include diffusion of solute through the lipid bilayer of a membrane.

What is active transport?

It is the process that is required to pump molecules against the gradient, both electrical and concentration.

Characteristics of active transport

  • To be able to displace sodium and potassium ions, there is the sodium-potassium pump, a transmembrane structure present in cells.

  • It consumes energy that comes from tissue metabolism and is used by transport pumps (ATPase type) that use the energy released by the hydrolysis of ATP to ADP.

Therefore, we can conclude that the active transport is carried out against a concentration gradient or electrical potentials, consequently, consumes energy, it doesn't include diffusion of solute through the lipid bilayer of a membrane.
