Which of the following statements regarding membrane transport is false?

Specific proteins are needed to transport polar and charged solutes effectively across cell membranes.
Sugars are always transported by active transport rather than by facilitated diffusion carriers.
Small molecules can transport across the cell membrane, but large molecules like proteins, usually are not transported.
Special protein that form membrane channels are used to transport ions.

Answered by admin @



'Membrane transport' is described as the 'transfer of solute particles via a transparent fence.'

The statement that asserts a false claim regarding the transport of membrane would be:

D). "Special protein that forms membrane channels are used to transport ions."

  • The statement regarding the special protein would be considered false as it incorrectly states that they are responsible for transferring ions.
  • The proteins that comprise the channel of the membrane are the aquaporins or water channel proteins.
  • It assists in allowing the water to enter and exit throughout the membrane quickly.
  • While ions are transported via 'ion channel' and not the aquaporins. Thus, option D is the correct answer.
