In _____, a series of increasingly electronegative components embedded in the in

In this stage, a series of increasingly electronegative components embedded in the inner mitochondrial membrane pass down electrons while pumping H+ ions from the Matrix (in mitochondria) / Stroma (in chloroplast) to the Inter-membrane space (in mitochondria) /Thylakoid space (in chloroplast). The potential energy created by the electrochemical gradient is known as the Proton-motive force. As H+ ions diffuse down their concentration gradient through ATP synthase that is embedded in the inner membrane, ATP is synthesized in the mitochondrial Matrix. Electrons are ultimately passed to O2, reducing it to H2O.

sound right to you?

Yes, but what are you putting in for that first empty space?
