During aerobic breakdown of a molecule of Glucose how many protons are carried from matrix of mitochondrion to perimitochondrial space through Complex III?

During aerobic breakdown of a molecule of Glucose there is formation of 10NADH and 2 FADH2. When these are oxidised through ETS, there is pumping of 4 X 12 protons = 48 from matrix to peri-mitochondrial space.
