The third stage of cellular respiration, occurring within the inner membrane of the mitochondria, in which the majority of the ATP are formed. In this process, electrons are transported along a chain of molecules, providing energy to pump hydrogen ions against their concentration gradient. When these hydrogen ions return down their concentration gradient, the energy released drives the synthesis of up to 32 ATP per molecule of glucose.
The final stage of aerobic respiration. The electron transport chain establishes an electrochemical gradient across the inner mitochondrial membrane that powers the synthesis of ATP in oxidative phosphorylation.
Sequence of membrane-bound electron carriers, which carry electrons from an electronegative electron donor to a more electropositive acceptor. In the electron transport chains of bacterial cell membranes, mitochondria and chloroplasts this transport is coupled to the movement of protons across the membrane, forming an electrochemical gradient that powers ATP synthesis.
Also known as the respiratory chain: The mitochondrial enzymes (also known as complexes I, II, III and IV) that are needed to generate the electron and proton "gradient" that is utilized by complex V to generate ATP.
a group of electron carriers in mitochondria that transport electrons to and from each other in a sequence, in order to generate ATP.
Also known as the respiratory chain. It is composed of the mitochondrial enzymes (also known as complexes I, II, III and IV) that transfer electrons from one complex to another, eventually resulting in the formation of ATP. Also referred to as the respiratory chain.
An electron transport chain (also called electron transport system (ETS) or electron transfer chain (ETC)) is a series of membrane-associated electron carriers 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 (photosynthesis). Organisms that use redox reactions to produce ATP are called chemotrophs.
