    Calcium is an important regulator of the citric acid cycle. Calcium is transported across the mitochondrial inner membrane by a Ca2+ uniporter that is driven by the negative potential inside the matrix. Part A Assuming a membrane potential across the inner membrane of 179 mV (inside negative), calculate the ratio of the [Ca2+] in the matrix to that in the cytoplasm ([Ca2+]m/[Ca2+]c) that would exist at equilibrium (i.e., ΔG=0). Part B Cytoplasmic [Ca2+] is on the order of 10−7M in...

    (1) Mitochondria regulate the concentration of calcium ions in the cytoplasm, by allowing the ions to equilibrate across the mitochondrial membrane. If the mitochondrion has a membrane potential of –150 mV relative to the cytoplasm, and the cytoplasmic concentration of Ca2+ is 1 μM, what is the mitochondrial Ca2+ concentration? Assume a temperature of 37 C. (2) The membrane calcium pump of the malarial parasite Trypanosoma cruzipumps out calcium ions from the parasite cell interior, hydrolyzing one molecule of ATP...
