Hydrogen ions ntws down lawv electrochemical gradient rov qab rau hauv matrix los ntawm ATP synthase channels uas ntes lawv lub zog los hloov ADP rau ATP. Daim ntawv ceeb toom tias cov txheej txheem rov tsim dua NAD+, muab cov khoom siv hluav taws xob uas xav tau hauv glycolysis.
hydrogen mus qhov twg tom qab ATP synthase?
Qhov no tshwm sim ntawm ATP synthase complex. Ib qho hydrogen ion nkag mus rau ATP synthase complex los ntawm qhov chaw nruab nrab thiab ib qho thib ob hydrogen ion tso nws rau ntawm qhov chaw matrix. Sab qaum ntawm ATP synthase complex rotates thaum ib tug tshiab hydrogen ion nkag.
Yuav ua li cas rau H + hauv cov saw hlau thauj hluav taws xob?
Nyob rau hauv cov saw hlau thauj khoom, cov qauv multiprotein tso tawm H + ions rau hauv qhov chaw nruab nrab. Raws li H + ions tau tso tawm, qhov concentration ntawm H + nyob rau hauv qhov chaw nruab nrab tau nce siab dua. Yog li ntawd, H + ions yuav pib ntws rov qab mus rau chromosomes matrix los ntawm ATP molecule.
Hydrogen thauj mus rau ETC li cas?
Thaum lub sijhawm thauj khoom siv hluav taws xob, lub zog yog siv los tso cov hydrogen ions hla cov mitochondrial puab daim nyias nyias, los ntawm cov matrix mus rau qhov chaw nruab nrab. Ib qho chemiosmotic gradient ua rau hydrogen ions ntws rov qab hla cov mitochondrial membrane rau hauv matrix, los ntawm ATP synthase, tsim ATP.
Hydrogen tuaj qhov twg hauvelectron thauj saw?
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.
