Oxidative Phosphorylation

Oxidative Phosphorylation

• Reduced NAD and FAD deliver the Hydrogen atom that they have accumulated to the electron transport chains. 
• The electron transport chains are present in the membranes of mitochondrial cristae. 
• These Hydrogen atoms disocciate into Hydrogen ions and electrons. 
• From this the high energy electrons are used in the synthesis of ATP by chemiosmosis. 
• Redox reactions release energy as the electrons reduce and oxidise electron carriers as they flow along the electron transport chain. 
• From this energy a proton gradient is created this leads to the diffusion of protons through ATP synthase, this results in the synthesis of ATP. 
• Once the electrons have travelled down the electron transport chain they combine with hydrogen ions…
