Where is the electron transport chain located?
The ETC is located in the inner mitochondrial membrane in eukaryotes. This membrane separates the mitochondrial matrix from the intermembrane space. The location is critical because the membrane’s impermeability to protons allows the establishment of a proton gradient. In prokaryotes, the chain is found in the plasma membrane, where it serves a similar function in ATP production.
