Question

Quizplus · Accepted Answer

Protein carriers are involved in active-mediated transport, which requires energy in the form of ATP.

Answer: A
 Protein carriers can also be involved in passive-mediated transport, which does not require energy and relies on concentration gradients.

Answer: D
 Protein carriers can facilitate diffusion of molecules across a membrane, especially those that are too large or polar to pass through the lipid bilayer.

Answer: C
 Protein carriers are not directly involved in osmosis, which is the passive movement of water molecules across a membrane from an area of low solute concentration to an area of high solute concentration. However, osmosis can be influenced by the presence of protein channels or carriers that allow the passage of water molecules.
