The ΔG°′ for the succinate dehydrogenase (Complex II) reaction is, which sufficient to drive ATP synthesis under the biochemical standard conditions. (Express your answer in kJ/mol and be sure to use the correct significant figures.)

Alpha particles have positive charge, beta particles have negative charge, and answer 4 just doesn’t make sense. thus, you are left with only one possible answer.

This is a solution, hope i could

Answer:             1.0  × 10⁻⁵ msolution:                     as we know ph is given as,                                    ph  = -log [h⁺]and,                                    [h⁺]  =  10^-ph    (1)putting value of ph in eq. 1,                                    [h⁺]  =  10⁻⁵                                    [h⁺]  =  1.0  × 10⁻⁵ m
