Question

Active and passive transport across the cell membrane

Answer 1

While active transport requires energy and work, passive transport does not. There are several different types of this easy movement of molecules. It could be as simple as molecules moving freely such as osmosis or diffusion. ... Since the cell membrane will not allow glucose to cross by diffusion, helpers are needed.

Answer 2

Passive transport is movement of substances across membrane without the utilization of energy(ATP). For Example: transportation of gases such as carbon dioxide and oxygen.

Active transport is movement of substances across membrane with the utilization of energy(ATP). For Example: transportation of ions such as sodium or potassium.
