| Video Discription | Electron transport chain: Electron transport system (ETS) is a chain of electron carriers consisting of NAD+, FAD+, CoQ and cytochromes (cyt. b, cyt. c, cyt. a and cyt. a3). The glucose molecule is completely oxidized by the end of the citric acid cycle. But, energy is not released, unless NADH2 and FADH2 are oxidized through electron transport system. Transfer of electrons and protons from NADH2 and FADH2 to oxygen through a series of components like flavoprotein, cytochrome is called electron transport chain. This process leads to coupling of electrons to form high-energy phosphate bonds in the form of ATP from ADP is called oxidative phosphorylation. The electron transport components are arranged in the inner membrane of mitochondria. According to modern concept, the electron carriers in the electron transport system are arranged in four complexes – complex I, complex II, complex III and complex IV. When NAD+ is a primary acceptor of electrons, the electrons are transported from complex I to II, II to III and then to complex IV. When electrons are transported from one complex to next complex, an ATP is produced. Thus, one molecule of NADH2 generates three ATPs. When FAD+ is a primary acceptor of electrons, the electrons are transported from complex II to III and then to complex IV. Thus, one molecule of FADH2 generates two ATPs. The molecular oxygen forms the terminal constituent of the electron transport system. It is the ultimate recipient of electrons and picks up the protons from the substrate to form water. Energy yield: Complete oxidation of one glucose molecule yields a net gain of 38ATP. Out of 38ATP molecules, 4ATP are obtained by direct substrate level phosphorylation, 30ATP through oxidation of NADH2 and 4ATP through oxidation of FADH2. Since, a large number of ATP molecules are produced in the mitochondria, they are called the ‘power houses of the cell’. Disclaimer This channel does not promote or encourage any illegal activities.
