Definition von electron transport chain im Englisch Englisch wörterbuch
(Biyoloji) The sequential transfer of electrons especially by cytochromes in cellular respiration from an oxidizable substrate to molecular oxygen by a series of oxidation-reduction reactions
(Biyoloji) An electron transport chain associates electron carriers and mediating biochemical reactions that produce adenosine triphosphate (ATP), which is the energy currency of life. Only two sources of energy are available to living organisms: oxidation-reduction (redox) reactions and sunlight (used for photosynthesis). Organisms that use redox reactions to produce ATP are called chemotrophs. Organisms that use sunlight are called phototrophs. Both chemotrophs and phototrophs utilize electron transport chains to convert energy into ATP
