what type of organism is the above one?
Coliform bacterium
Escherichia coli
Escherichia coli (), also known as E. coli (), is a Gram-negative, facultative anaerobic, rod-shaped, coliform bacterium of the genus "Escherichia" that is commonly found in the lower intestine of warm-blooded organisms (endotherms). 
is the electron transport chain part of oxidative phosphorylation Yes. It is the metabolic pathway in which cells use enzymes to oxidize nutrients, thereby releasing the chemical energy stored within in order to produce adenosine triphosphate (ATP) how is it related to chemiosmosis? When  the electron transport chain and the ATP synthase are embedded in a membrane, and energy is transferred from the electron transport chain to the ATP synthase by movements of protons across this membrane, in a process called "chemiosmosis in eukaryotes, where this process or pathway takes place? Inner membrane of the mitochondrion what is the first complex produce in this electron transport chain? NADH-coenzyme Q oxidoreductase what is this complex? It is the first protein in the electron transport chain. can you name some prokaryotes in which this etc can be seen? E.coli

Escherichia coli [SEP] Introduction
Escherichia coli (), also known as E. coli (), is a Gram-negative, facultative anaerobic, rod-shaped, coliform bacterium of the genus "Escherichia" that is commonly found in the lower intestine of warm-blooded organisms (endotherms). Most "E. coli" strains are harmless, but some serotypes (EPEC, ETEC etc.) can cause serious food poisoning in their hosts, and are occasionally responsible for food contamination incidents that prompt product recalls. The harmless strains are part of the normal microbiota of the gut, and can benefit their hosts by producing vitamin K, (which helps blood to clot) and preventing colonisation of the intestine with pathogenic bacteria, having a symbiotic relationship.
