Which of the following is NOT a correct statement about passive transport across the cell membrane

Question

Which of the following is NOT a correct statement about passive transport across the cell membrane?

a) Diffusion across an electrochemical gradient is one form of passive transport.
b) Facilitated diffusion by transport proteins is one form of passive transport.
c) Passive transport decreases free energy.
d) Passive transport may involve chemical energy in the form of ATP.
e) Passive transport increases entropy in a system.

Answer 1

Just to elaborate passive transport only allows the transport allows free energy transport, however the items usually moving across the membranes are very small, such as ions.

Answer 2

choice d is the correcg answer. The definition of passive transport is that no energy is used.

Answer 3

Choice D is the correct answer to this question. Passive transport does NOT require chemical energy in the form of ATP, whereas Active transport DOES.
