While it is tempting to focus on the names and numbers of the molecules and enzymes involved in oxidative phosphorylation, it is more important to emphasize ... WebThe proton gradient is generated by a series of oxidation-reduction reactions carried out by protein complexes that make up an electron transport chain in the membrane. The term oxidative phosphoryation, then, refers to phosphorylation of ADP to ATP coupled to oxidation-reduction reactions.
WebNov 12, 2024 · This proton-motive force is canonically described as the ATP synthesis driving force; however, it is often forgotten that the energy accumulated as H+ gradient is not fully interconverted... WebThe ATP synthase can also generate a proton gradient across a membrane under ATP-hydrolysis, that is, it also catalyzes the reverse reaction. The ATP synthase can be …
WebMar 6, 2024 · As electrons travel towards NADP+, they generate a proton gradient across the thylakoid membrane, which is used to drive synthesis of ATP. Thus NADPH, ATP, and … WebIn brief, the hypothesis was that most adenosine triphosphate (ATP) synthesis in respiring cells comes from the electrochemical gradient across the inner membranes of …
WebThe electron transport chain, often known as the ETC, is a collection of membrane-associated protein complexes that cooperate to produce a proton gradient across the mitochondrial inner membrane. The ATP synthase complex makes advantage of this proton gradient in the subsequent step of the production of ATP from ADP and inorganic …
