Chemiosmotic gradient definition biology
WebThe transport from cell to the neighboring one is achieved through relatively complex combination of several sub-processes. To explain the mechanism behind unique character of auxin transport through living cell files of the plant, the so-called chemiosmotic model was formulated. WebOxidative phosphorylation synthesizes the bulk of a cell’s ATP during cellular respiration. A proton-motive force, in the form of a large proton concentration difference across the membrane, provides the energy for the membrane-localized ATP synthase (a molecular machine) to make ATP from ADP and inorganic phosphate (Pi). The proton gradient is …

WebThe movement of ions across a selectively permeable membrane down an electrochemical gradient, usually understood to mean the respiratory chain in mitochondria. As the … WebA chemiosmotic gradient becomes charged by the potential energy of the electrons. Finally, the potential energy converts into chemical energy (ATP) by the ATP synthase complex. Thus, the electron transport system is an energy-producing mechanism, which obeys the principle of “ Takes energy to make energy ”.
