Thanks a lot, will rate lifesaver asap.

If you isolate mitochondria and place them in buffer with alow pH they begin to manufacture ATP. Why?
A.    Low pH increases the concentration of basecausing mitochondria to pump out H+ to the inter membrane spaceleading to ATP production.
B.    The high external acid concentration causes anincrease in H+ in the inter membrane space leading to increased ATPproduction by ATP synthetase.
C.     Low pH increases the acid concentration inthe mitochondrial matrix, a condition that normally causes ATPproduction.
D.     Low pH increases the OH- concentration in thematrix resulting in ATP production by ATP synthetase.

Which of the following statements about mitochondria is false?
A. They contain an inner and an outer membrane.
B. The region enclosed by the inner membrane is termed thematrix.
C. They contain DNA and ribosomes.
D. They are an important site for energy production in cells.
E. They contain stacked internal thylakoid membranes.

Explanation / Answer

B. The high external acidconcentration causes an increase in H+ in the intermembrane space leading to increased ATP production by ATPsynthetase.

E. They contain stacked internal thylakoidmembranes.
