Respiratory Control of the Electron Transport Chain (ETC)

Some Protons move through a symporter, which moves Phosphate into the Mitochondrial Matrix. The rest of the protons are typically moved through ATP Synthase.
When ATP is transported out of the mitochondria, ADP is simultaneously transported into the Mitochondria (The ATP-ADP Antiport).  When ATP is not used by the cell, there is no ADP available to antiport with ATP. So, ATP becomes backed up in the mitochondria.

- In this video, we explore how the electron transport chain is connected intimately with the production of ATP. This is known as respiratory control. When ATP is not exported from the mitochondria, what happens to the TCA cycle and ETC?
