Ferredoxin possesses iron-sulfur proteins that help in electron transfer. In radish there are 4 ferredoxins: 2 are root-specific (R-B1 and R-B2), one is present in both leaves and roots (L-A), and there is a minor form which is leaf specific (L-B). These prosthetic groups contain iron and sulfur atoms, organized in three different types of centers: 2Fe–2S, 4Fe–4 S, and 3Fe–4S. 1.

'All Intensive Purposes' or 'All Intents and Purposes'? (Biology) an iron- and sulphur-containing protein found in plants and microorganisms and involved in photosynthesis and nitrogen fixation Collins English Dictionary – Complete and Unabridged, 12th Edition 2014 © HarperCollins Publishers 1991, 1994, 1998, 2000, 2003, 2006, 2007, 2009, 2011, 2014 ... Ferredoxin: Definition. Ferredoxins are small proteins containing iron and sulfur atoms organized as iron-sulfur clusters. The iron-sulfur proteins are organized in clusters at the center in three different forms: 2Fe-2S, 3Fe-4S, and 4Fe-4S. neurula... or see Neurula on Thesaurus ... Full article >>> A Neurula is an embryo at the early stage of development in which neurulation occurs. Photosynthesis is defined as the process, used by green plants and photosynthetic bacteria, where electromagnetic radiation is converted to chemical energy and uses the energy of light to convert carbon dioxide and water to carbohydrates and oxygen. 3) The functions of ferredoxin are basic to cell chemistry. Type I photosystems use ferredoxin like iron-sulfur cluster proteins as terminal electron acceptors, while type II photosystems ultimately shuffle electrons to a quinone terminal electron acceptor. n. An iron-containing protein present in green plants and certain anaerobic bacteria that functions in electron transport reactions in biochemical processes, such as photosynthesis. Ferredoxin - NADP + Reductase. Ferredoxin is a small, iron-containing protein which acts as the electron acceptor associated with Photosystem I in photosynthesis.It accepts an electron and is reduced, giving it the capacity to pass on those electrons as part of the electron transport process.NADP + reductase catalyzes the reaction in which Ferredoxin is oxidized and NADP + is reduced to NADPH. Ferredoxin definition, any of a group of red-brown proteins containing iron and sulfur and acting as an electron carrier during photosynthesis, nitrogen fixation, or oxidation-reduction reactions. this process occurs in chloroplast which contains green pigments called chlorophyll. Ferredoxins are proteins containing FeS centres.
