Mitochondria can be isolated from cells and their production of ATP measured. You want to identify the mechanism of ATP production, so you isolate mitochondria, remove the outer membrane, and place them in a high pH solution. What will happen to the ATP
production if you start to lower the pH by adding hydrogen ions to the solution?
What will be an ideal response?
As hydrogen ion concentration outside the mitochondria increases, hydrogen ions will flow into the mitochondria through the ATP synthase. This will increase ATP production.
