Chemiosmosis Chemiosmosis Chemiosmosis is the diffusion of ions across a selectively-permeable membrane. More specifically, it relates to the generation of ATP by the movement of hydrogen ions across a membrane during cellular respiration.An Ion gradient has potential energy and...
[23,24]. The reaction sequence is simple and involves aformate dehydrogenasethat oxidizes formate and channels electrons to a membrane-bound hydrogenase, very similar to theenzymedescribed above forP.furiosus[22,23].Electron transferto protons leads to the generation of an ion gradient that then ...
The production of ATP within the mitochondria involves two metabolic cycles called the "Krebs" or "citric acid" cycle, and the oxidative phosphorylation electron transport chain.… 452 Words 2 Pages Good Essays Read More Cell Energy The electron transport system, stage three of cellular ...
In evolutionary terms, cooperation usually involves costs and thus is not an automatic outcome. Hosts and symbionts may respond to divergent selective forces. A defecting symbiont can be selected to sequester resources from the host and symbiont community and to use these resources for its ...
Synthesis of ATP by chemiosmosis today involves generation of an ion gradient by means of vectorial electron transfer from a donor to an acceptor. We argue that the first donor was hydrogen and the first acceptor CO2. 展开 关键词:alkaline hydrothermal vents ATPase chemiosmosis LUCA proton ...
