What is the function of the electron transport system (ETS)? It takes electron-carrier molecules made during glycolysis and the Krebs cycle and uses them to make ATP. The ETS takes place in the cristae of the mitochondria and provides 34 molecules of ATP for every one glucose molecule that enters glycolysis. It breaks down a six-carbon sugar into two three-carbon pyruvic acid molecules. For each six-carbon sugar, two molecules of ATP and one molecule of NADH are formed. This process takes place in the thylakoid membrane. It takes six-carbon sugar molecules made during the Krebs cycle and uses them to make ADP. The ETS takes place in the granum of the mitochondria and provides 16 molecules of ADP for every one glucose molecule that enters glycolysis. It metabolizes pyruvic acid to form ATP, NADH, and FADH2. Both NADH and FADH2 are then used to make four molecules of ADP using electron transfer. The stroma of the cell is the site of this cyclical process.

This potential is then used to drive ATP synthase and produce ATP from ADP and a phosphate group. Biology textbooks often state that 38 ATP molecules can be made per oxidised glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).
"Function of Electron transport chain (ETS):
• Electron transport chains are utilized for deriving energy by means of redox responses from mechanisms such as photosynthesis, oxidation of sugars, and cellular respiration.
• In eukaryotes, an essential electron transport chain is found in the inward mitochondrial film where it fills in as the site of oxidative phosphorylation through the activity of ATP synthase. It is additionally found in the thylakoid film of the chloroplast in photosynthetic eukaryotes. In microscopic organisms, the electron transport chain is situated in their cell film.
• Electron transport chains are real destinations of untimely electron spillage to oxygen, producing superoxide and conceivably bringing about expanded oxidative pressure.
• The electron transport chain comprises of a spatially isolated arrangement of redox responses in which electrons are exchanged from a giver atom to an acceptor particle. The fundamental power driving these responses is the Gibbs free vitality of the reactants and items. The Gibbs free vitality is the vitality accessible (""free"") to do work. Any response that diminishes the general Gibbs free vitality of a framework is thermodynamically unconstrained."
