KR Wong JT Buckley. A proton motive force is established via the action of either electron transport systems or instead membrane transport proteins that are known as proton pumps. Brown fat cells have a specialized protein that dissipates the proton-motive force across the mitochondrial membranes.
Department of Biochemistry and Microbiology University of Victoria BC Canada. In most cases the proton-motive force is generated by an electron transport chain which acts as a proton pump using the Gibbs free energy of redox reactions to pump protons hydrogen ions out across the membrane separating the charge across the membrane. The latter stimulated antibiotic uptake as determined using fluorescently labelled tobramycin in combination with flow cytometry analysis.
Chemicalcontribution G chem nRT ln H in H out n number of protons translocated p - 0059 V pH p - 017 - 003 - 020 V 2. This potential energy is used for the synthesis of ATP by oxidative phosphorylation or photophosphorylation respectively. What is the moving unitrotor composed of.
The proton motive force occurs when the cell membrane becomes energized due to electron transport reactions by the electron carriers embedded in it. This creates ATP while using the proton motive force created by the electron transport chain as a source of energy. The proton-motive force created by the pumping out of protons by the respiratory chain complexes is in the mitochondria of most tissues mainly used to translocate protons through the ATP synthase complex leading to the formation of ATP from adenosine diphosphate ADP and phosphate.
