What is this the symbol for in the protonmotive force equation?

Put the Protonmotive force equation in order; Change in PMF = _ - (_ x _) A = Farraday constant B = Change in pH C= Change in electrical potential

Short circuiting the protonmotive force generation system causes the energy to be released as heat

The number of protons pumped in a full cycle is cell dependent

Put the Protonmotive force equation in order; Change in PMF = _ - (_ x _)
A = Farraday constant
B = Change in pH
C= Change in electrical potential
