Why are there apparently no electron transport chains in eukaryotic membranes? The mitochondrial and chloroplast ETCs are in the inner, bacterial membrane and I can not find any example of an ETC in a eukaryotic membrane. I would think that such a powerful mechanism for generating ATP would evolve at least twice (as useful as the camera eye, right?) or be co-opted. Are they there and I am unaware?
