Oxidative Phosphorylation1Oxidative PhosphorylationHow are the electrons in NADH and FADH2used to make ATP during cellular respiration?Why?The final phase of cellular respiration isoxidative phosphorylation. Both the electron transport chainand chemiosmosis make up oxidative phosphorylation. During this phase of cellular respiration, all of theNADH and FADH2that were produced in other phases of cellular respiration (glycolysis, the link reac-tion, and Krebs cycle) are used to make ATP. The process occurs in the protein complexes embedded inthe inner mitochondrial membrane.Model 1 – Electron Transport ChainH+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+H+OuterMitochondrialMembraneIntermembraneSpaceMitochondrialMatrixInnerMitochondrialMembraneHigh potentialenergy electronNADHFADH22H2ONAD++ H+FAD++ 2H+O2+ 4H+Embeddedprotein channelsH+H+H+1.

Refer to Model 1.a.Describe the region in Model 1 where the highest concentration of hydrogen ion (H+) islocated.b.According to Model 1, how do the hydrogen ions reach this area?3. Explain why energy is required to move the hydrogen ions across the membrane in the directionindicated in Model 1.
