Hauv mitochondria, cov hluav taws xob hluav taws xob siab tau muab rho tawm los ntawm cov khoom noj molecule (los ntawm cov tshuaj tiv thaiv redox) thaum nyob rau hauv chloroplast qhov chaw yog los ntawm cov photons ntes los ntawm lub teeb qhov chaw. Cov proton (H+) gradient cov ntaub ntawv los ntawm H+ ions accumulating nyob rau hauv lub thylakoid compartment (piv txwv li qhov chaw nyob rau hauv lub thylakoid.).
hydrogens mus qhov twg thaum chemiosmosis?
Hydrogen ions nyob rau hauv qhov chaw matrix tsuas tuaj yeem dhau dhau ntawm cov mitochondrial membrane innerlos ntawm cov membrane protein hu ua ATP synthase. Raws li protons txav los ntawm ATP synthase, ADP hloov mus rau ATP. Kev tsim cov ATP siv cov txheej txheem ntawm chemiosmosis hauv mitochondria yog hu ua oxidative phosphorylation.
Chemiosmosis tshwm sim nyob qhov twg hauv mitochondria?
Chemiosmosis ua haujlwm vim yog qhov hu ua electron thauj saw hlau (ETC) uas nyob hauv lub puab mitochondrial membrane. Lub ETC yog ib pab pawg ntawm cov proteins uas ua haujlwm ua ke thiab kis electrons rau ib leeg zoo li yog qos yaj ywm kub. ETC muaj peb cov proteins ua cov twj hydrogen ion.
H+ nyob qhov twg hauv cellular respiration?
Hauv cov hlwb prokaryotic, H+ ntws los ntawm sab nraud ntawm cytoplasmic membrane rau hauv cytoplasm, whereas hauv eukaryotic mitochondria, H+ ntws los ntawm intermembrane qhov chaw mus rau mitochondrial matrix.
Hydrogen ions tuaj qhov twg hauv cov saw hlau thauj hluav taws xob?
Tshwj xeeb, nws yog muab los ntawm txheej txheem uas pib nrog kev txav hluav taws xob los ntawm cov khoom siv hluav taws xob uas ua rau muaj kev cuam tshuam redox: cov saw hlau thauj electron. Qhov no ua rau cov hydrogen ions mus rau hauv qhov chaw matrix.
