7.2: The Electron Transport Chain (ETC) - Biology LibreTexts

Web3. jan 2024 · All cells use an electron transport chain (ETC) to oxidize substrates in exergonic reactions. The electron flow from reduced substrates through an ETC is like the movement of electrons between the poles of a battery. In the case of the battery, the electron flow releases free energy to power a motor, light, cell phone, etc. WebAsha Kumari, in Sweet Biochemistry, 2024. Abstract. The electron transport chain is a mitochondrial pathway in which electrons move across a redox span of 1.1 V from … Redox is a type of chemical reaction in which the oxidation states of substrate change. Oxidation is the loss of electrons or an increase in the oxidation state, while reduction is the gain of electrons or a decrease in the oxidation state. There are two classes of redox reactions: Electron-transfer – Only one … Zobraziť viac "Redox" is a combination of the words "reduction" and "oxidation". The term "redox" was first used in 1928. The processes of oxidation and reduction occur simultaneously and cannot occur independently. In … Zobraziť viac Each half-reaction has a standard electrode potential (E cell), which is equal to the potential difference or voltage at equilibrium under standard conditions of an electrochemical cell Zobraziť viac Cathodic protection is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. A simple method of protection connects protected metal to a more easily corroded "sacrificial anode" to act as the anode. … Zobraziť viac Minerals are generally oxidized derivatives of metals. Iron is mined as its magnetite (Fe3O4). Titanium is mined as its dioxide, usually in the form of rutile (TiO2). To obtain the corresponding metals, these oxides must be reduced, which is often achieved by … Zobraziť viac Redox reactions can occur slowly, as in the formation of rust, or rapidly, as in the case of burning fuel. Electron transfer reactions are generally fast, occurring within the time of mixing. The mechanisms of atom-transfer reactions are … Zobraziť viac In the reaction between hydrogen and fluorine, hydrogen is being oxidized and fluorine is being reduced: H2 + F2 → 2 HF This reaction is … Zobraziť viac Many important biological processes involve redox reactions. Before some of these processes can begin iron must be assimilated from … Zobraziť viac coryneum
