3) When the movie ends, all the movie-goers pour out of the theatre through multiple exits into the empty lobby. If they all cruise easily through the multiple, unguarded exits, with no one blocking their way or monitoring their progress what transport process does this most resemble AND WHY?


4) In the scenario from Question 3, if we assume that inside the theatre is one biological compartment, and the lobby is a second biological compartment, and after the movie ends, the movie-goers are free to pass freely between the theatre and the lobby as they wish, how many of the moviegoers would we expect to end up in the lobby, and how many would we expect to stay in the theatre? AND WHY?

3) Cell in Very much hypotonic solution or Cytolysis

4) Simple diffusion. Equal on both sides.
( In real all will be outside- Nobody want to seat in empty theater with no movie Posted Image )

Can you please help me with this ones.


1) Hundreds of people are waiting outside an empty movie theatre waiting to run in and claim seats to see Puss in Boots. 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?

2) An hour later, the same theatre is completely filled with a movie-goer in every seat plus another 100 people standing in the aisles and crowding the entrance to the theatre. One last person is outside the turnstile, desperately wanting to get in the theatre. If the usher pushes all the people crowding the door out of the way and shoves the last person inside the door to the theatre, what transport process does this most resemble AND WHY?

1) Facilitated Diffusion - Facilitated diffusion inclues symporter, antiporter etc. - Ticket serve function of symporter ion in this case

2) Active transport- When molecules/Ions are already more inside biological system energy is needed to push more molecules into it.

@prabhubct: Obvious homework/exam questions please try to get the questioner to answer the question before you supply the answer fully. Helps the asker learn and makes sure that if they are exam questions, then the delay will usually be enough to make sure that they can't use your answers for cheating...
