What would be the effect on ATP production of decreasing the pH inside the mitochondrial matrix? Explain

propose a mechanism that could allow pyruvate to cross the mitochondrial memebranes to enter the mitochondrial matrix

You are given a suspension of purified mitochondria that are known to have adequate reserves of NAD+, FAD, and ADP/inorganic phosphate. Assume that the mitochondrial preparation you are working with is free of cytosolic components (enzymes and metabolites) and assume that all the compounds listed below can cross both mitochondrial membranes, When glucose is added to this suspension: a. What is the effect on oxygen consumption by the purified mitochondria? b. Explain your answer above. When citrate is added to this suspension: c. What is the effect on oxygen consumption by the purified mitochondria? d. Explain your answer above.

Both mitochondria and chloroplasts use a proton gradient to drive ATP synthesis, but in different locations. What is the major structural difference, that is related to the proton gradient, between mitochondria and chloroplasts, and where is ATP generated in each?

There are some drugs that can inhibit the activity of ATP synthase. How does this affect the pH of the inner membrane space and the mitochondrial matrix?
