(B) Bar graph representation of basal respiration measured in (B) for cWT, cWT+ATAD1 , PEX3-/-, PEX3-/-+ATAD1, cWT-ATAD1 , and PEX3-/--atad1 cells. (C) Bar graph representation of maximal respiration measured in (B) for cWT, cWT+ATAD1 , PEX3-/-, PEX3-/-+ATAD1, cWT-ATAD1 and PEX3-/- -atad1 cells. (D) Bar graph representation of calculated respiratory spare capacity (uncoupled respiration minus basal respiration) measured in (B) for cWT, cWT+ATAD1 , PEX3-/-, PEX3-/-+ATAD1, cWT-ATAD1, and PEX3-/--atad1 cells.
