Oxidative Phosphorylation – Class 11 | Chapter – 14 | Biology Short Notes Series PDF

Oxidative Phosphorylation: The metabolic pathway through which the electron passes, starting with one transporter and then onto the next, is known as the electron transport framework (ETS). The electron transport framework happens in the inward mitochondrial layer. The electron transport chain contains the accompanying:

  • Complex I: NADH dehydrogenase
  • Complex II: succinate dehydrogenase
  • Complex III: cytochromes bc 1
  • Complex IV: cytochromes a-a3
  • Complex V: ATP synthase

NADH2 is oxidized by NADH dehydrogenase and electrons are then moved to ubiquinone situated in the inward mitochondrial film. FADH2 is oxidized by succinate dehydrogenase and moved electrons to ubiquinone. The decreased ubiquinone is then oxidized with the move of electrons by means of cytochromes bc 1 complex to cytochrome c. Cytochrome c is a little protein joined to the external surface of the internal film and moves electrons from complex III to complex IV. At the point when electrons moved to start with one transporter and then onto the next by means of mind-boggling I to complex IV, they are coupled to ATP amalgamation of ATP from ADP and Pi (inorganic phosphate) Oxygen assumes an essential part in eliminating electrons and hydrogen particles lastly help in the development of H₂

Oxidative Phosphorylation

Oxidative Phosphorylation

Oxidative phosphorylation is the terminal oxidation of high-impact breath. It is the cycle where ATP is shaped with the assistance of electrons moved from the electron transport chain. F1 molecule is the site of oxidative phosphorylation. It contains an ATP synthase catalyst. At the point when the convergence of proton is higher at F0 than in F1 molecule, ATP synthase became dynamic for ATP blend. The energy from the proton slope is utilized to append the phosphate radical and ADP by high energy bond to produce ATP
