ATPsynthesis depends on the occurrence of electron flow in mitochondria O, consumption was neither observed ifADP was not added to the suspension, although a reductant is provided The o, consumption was also not observed in the presence of inhibitors of ATP synthase(e.g oligomycin or venturicidin) Electron flow also depends on ATP synthesis. ATP synthesis depends on the occurrence of electron flow in mitochondria.  O2 consumption was neither observed if ADP was not added to the suspension, although a reductant is provided.  The O2 consumption was also not observed in the presence of inhibitors of ATP synthase (e.g., oligomycin or venturicidin).  Electron flow also depends on ATP synthesis!
