In order to leave Eukaryote we will need to go through the membrane using a channel made of ______________.

festinger · Answer

Without more information about the options available I'll just venture a guess: a channel made of protein. These are called protein channels and they facilitate movement of molecules of a specific size and charge. http://classes.midlandstech.edu/carterp/Courses/bio210/chap03/210_figure_03_07_labeled.jpg

we will also be moving against the concentration gradient (active transport) which requires energy in the form of ____________.

Energy in the form of ATP. This process is called exocytosis. http://archive.cnx.org/resources/cadd933752e6600a269e65c34f38bc9380363080/Figure_03_06_02.jpg

Why doesn't the cell have ATP laying around to use?

Depends on the cell and condition, sometimes they can regenerate ATP from ADP. If there is lack of oxygen fermentation can occur.

festinger · Answer

I am assuming that the cell is healthy... sometimes the electron transport chain doesn't happen because the mitochondria is damaged etc. ATP production relies on glucose. If there isn't glucose and the cell cannot find ways to produce glucose then the cell may not be able to produce ATP.
