Chemistry
In isolated thylakoid membranes you measure, through the use ofmolecular probes, a transmembrane potential of delta psi = + 60 mVand a delta pH of 2- (inside acidic) across the thylakoid membrane.A) How much free energy is yielded by moving 1 mole of protonsoutward through the H+-ATPase under these conditions of delta psiand delta pH? B) If there are 10 c- subunits in the chloroplastATPase (cFo), how much energy is available to synthesize eachATP?
