where are the proteins of the electrons transport chain located
inner mitochondrial membrane
Electron transport chains are located there are many different electron donors and electron acceptors. Reverse electron transport is the most important in prokaryotic electron transport chains.
Electron transport chains
Electron transport occurs in the mitochondria of eukaryotic cells. Specifically, the four protein complexes of the electron transport chain (ETC) exist as transmembrane complexes in the inner membrane of the mitochondria.
An electron transport chain(ETC) couples a chemical reaction between an electron donor (such as NADH) and an electron acceptor (such as O2) to the transfer of H+ ions across a membrane, through a set of mediating biochemical reactions. These H+ ions are used to produce adenosine triphosphate (ATP), the main energy intermediate in living organisms, as they move back across the membrane. Electron transport chains are used for extracting energy from sunlight (photosynthesis) and from redox reactions such as the oxidation of sugars (respiration). In chloroplasts, light drives the conversion of water to oxygen and NADP+ to NADPH and a transfer of H+ ions. NADPH is used as an electron donor for carbon fixation. In mitochondria, it is the conversion of oxygen to water, NADH to NAD+ and succinate to fumarate that drives the transfer of H+ ions. While some bacteria have electron transport chains similar to those in chloroplasts or mitochondria, other bacteria use different electron donors and acceptors. Both the respiratory and photosynthetic electron transport chains are major sites of premature electron leakage to oxygen, thus being major sites of superoxide production and drivers of oxidative stress.

Mitochondrial and thylakoid membranes are sites of electron transport chains. They both use ATP synthase proteins in ATP production.
Electron transport chains are present in mitochondria. The products of the electron transport chains are energy in the form of thermodynamics and water which is reduced from oxygen.

This depends on whether you are a eukaryote, bacteria or archaea. In eukaryotes, the electron transport chain components are on the mitochondrial membrane.In bacteria and archaea, since there are no membrane-enclosed compartments, they are on the cellular membrane.
