ADP/ATP transport to/from the matrix of a mitochondria...
« on: May 28, 2014, 09:35:44 PM »
...How?

I've seen these little flip-things (can't recall the name) that swap a ATP for a ADP from the cytoplasm, but does it just take the ADP and ATP to/from the intermembrane space, or ADP and ATP all the way to/from the matrix?

If the former, then how does the ADP get in the matrix/the ATP get out?

Briefly, we don't really know exactly how.  However, here's a quick reference I found on Google: http://www.ncbi.nlm.nih.gov/books/NBK22470/  Perhaps your textbook has something similar.  However, the absolute specifics are likely too incompletely known, and too complicated to describe in forum posts.
Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

IIUC, the outer mitochondrial membrane has pores which allow the passage of small molecules between the cytoplasm and the intermembrane space.  The translocase is an antiporter found on the inner mitochondrial membrane (which separates the matrix from the IM space).
