You must try the simulation before answering the questions.
Click on the buttons at the top and bottom to release different types of molecules outside and inside the cell, respectively. The simulation can be run with or without channels and carriers by clicking on the boxes at the bottom. You can follow the movement of the different molecules by clicking on the graph button at the bottom.
