If you isolate mitochondria and place them in buffer with a low pH they begin to manufacture ATP. Why?

A.	Low pH increases the concentration of base causing mitochondria to pump out H+ to the inter membrane space leading to ATP production.
B.	The high external acid concentration causes an increase in H+ in the inter membrane space leading to increased ATP production by ATP synthetase.
C.	Low pH increases the acid concentration in the mitochondrial matrix, a condition that normally causes ATP production.
D.	Low pH increases the OH- concentration in the matrix resulting in ATP production by ATP synthetase.
