Complex V of ETS(respiration)?

Location: Inner mitochondrial membrane. Seen in the mitochondrial respiratory chain
Composition
> 80 peptides organized in 5 enzymatic complexes (I-V)
Electron shuttle molecules: Coenzyme Q (CoQ); Cytochrome c (Cyt c)
Overall actions: Produces ATP from the reduction of oxygen to generate energy for cellular function
Pathway
Receives electrons generated by donors in intermediary metabolism
Electrons sequentially transferred through redox groups to final acceptor, oxygen
Free energy generated: Used to pump protons from mitochondrial matrix to intermembrane space
Generates electrochemical gradient across inner mitochondrial membrane
Protein flux back into mitochondrial matrix through Complex V is coupled to ATP synthesis.

Couples proton gradient generated by respiratory chain to ATP synthesis.
Proton flow from intermembrane space to matrix
Conversion of ADP + inorganic phosphate to ATP
