Cov khoom kawg ntawm electron thauj saw yog dej thiab ATP. Ntau qhov sib xyaw nruab nrab ntawm lub voj voog citric acid tuaj yeem hloov mus rau hauv anabolism ntawm lwm cov biochemical molecules, xws li cov amino acids tsis tseem ceeb, suab thaj, thiab lipids.

Kuj paub, dab tsi yog cov khoom tsim los ntawm cov saw hlau thauj khoom?

Hluav taws xob Cov cab kuj raug txo thaum lub sij hawm glycolysis thiab citric acid voj voog rau NADH + H + thiab FADH2. Cov neeg nqa khoom no ces pub dawb electrons thiab cov protons mus rau qhov hluav taws xob carrier proteins ntawm cov hlab ntsha electron thauj saw . Qhov kawg hluav taws xob txais yog oxygen. Ua ke nrog oxygen, electrons thiab protons tsim molecules ntawm dej.

Ib sab saum toj no, lub hom phiaj ntawm cov saw hlau thauj electron yog dab tsi? Lub ntsiab Lub hom phiaj ntawm cov saw hlau thauj electron yog tsim kom muaj qhov seem ntawm hydrogen ions (protons) nyob rau hauv qhov chaw interemembrane thiaj li yuav muaj qhov concentration gradient piv rau cov matrix ntawm mitochondria.

Tsis tas li ntawd, cov khoom thiab cov reactants ntawm electron thauj saw yog dab tsi?

Cov ntsiab lus hauv cov teeb no (10)

  • Reactants thiab cov khoom ntawm ETC. Electron Transport reactants: Hydrogen ions, oxygen, NADH, FADH2 Khoom: Dej thiab ATP (2 e- + 2 H + 1/2 O2 = H20)
  • Complex I. NADH dehydrogenase.
  • Complex II.
  • Complex III.
  • Complex IV.
  • Lub luag haujlwm ntawm Oxygen hauv ETC.
  • Phosphorylation ntawm substrate.
  • Oxidative Phosphorylation.

Muaj pes tsawg ATP raug tsim nyob rau hauv cov saw hlau thauj electron?
