Apart from fermentation, most bioenergetic pathways have a similar general structure, with an electron transport chain composed of protein complexes acting as electron donors and acceptors, as well as a central cytochrome complex, mobile electron carriers, and an ATP synthase.
Pertinent Vocabulary/Background (Mauseth, 2003; Taiz & Zeiger, 2002) Accessory Pigment A pigment with an absorption spectrum that differs from that of chlorophyll a, and that transfers its absorbed energy to the chlorophyll a in the reaction center Antenna Complex A group of pigments that absorbs energy and passes it to the reaction center Carotenes A class of carotenoids found in the antenna complex Electron Transport Chain A series of electron carriers that transfer electrons from a donor, which becomes oxidized, to an acceptor, which becomes reduced Excited State When a quantum of light is absorbed by a pigment, one electron is raised from its stable or ground state to a higher energy orbital; that is, the electron and thus the pigment are said to be "excited.
Most of the energy of fatty acids is extracted through oxidation to produce the reduced forms of high-energy electron carriers nicotinamide adenine dinucleotide (NADH) and flavin adenine dinucleotide ([FADH.
This is a logical approach, given that natural photosynthesis involves excitation of electrons by light and so-called 'redox' reactions in which electrons are passed through a series of electron carriers.
These efficient electron carriers have served the same purpose in other alternative solar cells.
