Oligomycin: a complex V inhibitor, derive ATP-linked respiration and proton leak respiration. 

FCCP: ie. proton (H⁺), for the maximum capacity of H⁺

Rotenone: shut down ETC (electron transport chain) function, revealing the non-mitochondrial respiration. non-mutdrome consumption

They use FCCP (1 mmol), not 2 mmol. The Max. FCCP is optimized for endothelial cells.
