WebThe two NADH produced in the cytoplasm produces 2 to 3 ATP each (4 to 6 total) by the electron transport system, the 8 NADH produced in the mitochondriaproduces three ATP each (24 total), and the 2 FADH2adds its electrons to the electron transport system at a lower level than NADH, so they produce two ATP each (4 total). WebUsing the Bohr model, determine the lowest possible energy, in joules, for the electron in the Li 2+ ion. Using the Bohr model, determine the lowest possible energy for the electron in the He + ion. Solution. −8.716 × 10 −18 J.
