Study Notes
Electron Transport Chain and ATP Synthesis
- The process that generates a proton gradient across the inner mitochondrial membrane is the electron transport chain.
- The purpose of ATP Synthase in oxidative phosphorylation is to use the proton gradient to synthesize ATP from ADP and inorganic phosphate (Pi).
- The electron transport chain oxidizes NADH and FADH2 molecules.
- The proton gradient generated by the electron transport chain drives the production of ATP through the process of chemiosmosis.
Mitochondria and Aerobic Respiration
- The role of the mitochondria in aerobic respiration is to generate most of the ATP through the process of oxidative phosphorylation.
- Mitochondria are the site where the electron transport chain, oxidative phosphorylation, and citric acid cycle take place.
Citric Acid Cycle
- The main function of the citric acid cycle is to produce NADH and FADH2, which are then oxidized via the electron transport chain.
- The citric acid cycle generates NADH, FADH2, ATP, and coenzyme A, which are then used in the electron transport chain.
- NADH and FADH2 molecules are removed in the electron transport chain in the mitochondria.
