what are the role of this organism in disease causing?
Their presence is used to indicate that other pathogenic organisms of fecal origin may be present, which  include disease-causing bacteria, viruses, or protozoa and many multicellular parasite. It is performed in aerobic or anaerobic conditions.
Coliform bacteria
While coliforms themselves are not normally causes of serious illness, they are easy to culture, and their presence is used to indicate that other pathogenic organisms of fecal origin may be present. Such pathogens include disease-causing bacteria, viruses, or protozoa and many multicellular parasites. Coliform procedures are performed in aerobic or anaerobic conditions.
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 what type of organism is the above one? Coliform bacterium do they have any therapeutic use? Ferment lactose

Coliform bacteria [SEP] Introduction
Escherichia coli have an incubation period of 12–72 hours with the optimal growth temperature being 37°C. Unlike the general coliform group, "E. coli" are almost exclusively of fecal origin and their presence is thus an effective confirmation of fecal contamination. Most strains of "E. coli" are harmless, but some can cause serious illness in humans. Infection symptoms and signs include bloody diarrhea, stomach cramps, vomiting and occasionally, fever. The bacteria can also cause pneumonia, other respiratory illnesses and urinary tract infections.
