Hundreds of people are waiting outside an empty movie theatre waiting to run in and claim seats to see rogue one. all entrance to the theatre is through a single turnstile, monitored by an usher checking tickets. when the theatre doors open and people first start moving into the theatre, which transport process does this most resemble (simple diffusion, facilitated diffusion, or active transport) and why?

Facilitated diffusion

Explanation:

Diffusion is simply the movement of molecules from the region of higher concentration to the region of lower concentration. Diffusion can be divided into into types namely;

Simple diffusion is simply the movement of solute/ion molecules downward the concentration gradient from the region of high solute/ion concentration to the region of low concentration.

Osmosis is usually referred to the diffusion of water molecules from the region of high water/low solute concentration to the region of low water/high solute concentration. Osmosis essentially has to do with the movement of water molecules.

Facilitated diffusion is the movement of molecules/ions downward a concentration gradient with the assistance of carrier or channel proteins.

Active transport on the other hand is the movement of molecules or ion against concentration gradients from the region of low concentration to the region of high concentration. It usually involves the use of energy in the form of ATP.

The movement of people into the theatre can be viewed as a form of facilitated diffusion. The molecule in question are the people that want to see Rogue One while the ticket which grants them access into the theatre  is the carrier or channel protein. Without the ticket, the usher will not grant them access into the theatre. The usher seems to be acting like a membrane in this case.

The correct answer is facilitated diffusion.
