10615 Lecture Notes Amber Hall 0 Stage 3 electron transport chain oxidative phosphorylation Takes place in mitochondria Proteins cytochromes pass electrons NAD and FAD are oxidized Figure 69 3 proton pumps 0 Pumps protons from matrix across the mitochondrial membrane into the intermembrane space 0 Movement of electrons is an energy source I ATP synthase enzyme that synthesizes ATP I Also a passage way for protons I Intermembrane space high concentration because of proton pumps I For every glucose that started glycolysis we get 3234 ATP Where does this stage of energy production take place What s become of our electron shuttles now What is the importance of the proton pumps How do the H ions get back to the mitochondrial matrix Through the ATP synthase What is the job of the ATP syntheses What happens to the oxygen in the electron transport chain Why is this process called quotoxidative phosphorylation o Harvesting energy the anaerobic way Pyruvate with no oxygen or C02 makes ethanol alcohol Pyruvate with no oxygen creating lactic acid caused by excessive exercise No new ATPs 0 Your food and metabolism Figure 613 0 Thought questions Why must you breathe Why do you breathe really hard after strenuous muscleburning exercise Why do athletes stock up on carbs before a big sporting event
