To explain:
How Desulfovibrio can grow anaerobically with H2 as electron donor and SO42- as electron acceptor (which is reduced to H2S). Based on this information and the data in Table A1.2 (Appendix 1), which components could not exist in the electron transport chain of this organism and why: cytochrome c, ubiquinone, cytochrome c3, cytochrome aa3, ferredoxin.
Introduction:
Electron transport chain is a series of energy reaction in which electrons are transferred from one energy level to another through oxidation and reduction potential across the membranes in mitochondria. The electron transport chain is important in energy production and transfer which is mediated by enzymes like cytochrome oxidase.
