Calculate the proton-motive force that would be formed across a thylakoid membrane that maintained a 10,000 -fold difference in $\left[\mathrm{H}^{+}\right]$ and no electric potential difference. (The equation for protonmotive force is on page 186 .) Given what you know about photosynthesis, which side of the thylakoid membrane (lumen or stroma) is the one with the higher proton concentration?
Calculate the free energy of the proton motive force if the mitochondrial matrix has a pH of 7 and the intermembrane space is pH 5. The ΔV is 0.14. The Faraday constant, F, is 96.49 kJ mol^-1 V^-1. R = 8.3145 J mol^-1 K^-1.

If two electrons are each $1.50 \times$ $10^{-10} \mathrm{m}$ from a proton, as shown in Fig. $\mathrm{E} 21.37,$ find the magnitude and direction of the net electric force they will exert on the proton.
