"Oxidative phosphorylation is occurring in an isolated mitochondria suspended in a solution buffered at pH = 7.4. The pH of the matrix is measured at 7.7.
a) Calculate i) the [H+] in the external solution and ii) the [H+] in the matrix.
b) Calculate the # of protons in a single mitochondrion assuming the matrix is a spherical compartment with a diameter of 1.5 micrometres."
Note: I've already calculated the two [H+] needed to calculate b), but I can't seem to figure b) out at all. I know that I need to calculate the volume, which I did, but after that I'm stuck... |
