Prokaryotes energy flow

In Chapter 10 the basic principles of oxidative phosphorylation, the complex mechanism by which modem aerobic cells manufacture ATP, are described. The discussion begins with a review of the electron transport system in which electrons are donated by reduced coenzymes to the electron transport chain (ETC). The ETC is a series of electron carriers in the inner membrane of the mitochondria of eukaryotes and the plasma membrane of aerobic prokaryotes. This is followed by a description of chemiosmosis, the means by which the energy extracted from electron flow is captured and used to synthesize ATP. Chapter 10 ends with a discussion of the formation of toxic oxygen products and the strategies that cells use to protect themselves. 

Respiratory chain, eleetrou tramport cbain a series of redox catalysts which transport electrons from respiratory substrates to oxygen. The energy of this electron flow may be used in the synthesis of ATP. The coupling of ATP synthesis with electron transport in the R.c. is known as Oxidative phosphorylation (see). The R.c. complex is located in the inner mitochondrial membrane of eukaryotes, and in the cell membrane of prokaryotes. It is fonctionally closely associated with the enzymes of the Tricarboxylic acid cycle (see) which supply reducing equivalents, mostly in the form of NADH, with some FADHj. De-...
