WHAT HAPPENS NEXT?

Learn about the journey of NADH and pyruvic acid in the presence or absence of oxygen, the reactions in the mitochondria and cytoplasm, the significance of CO2 production, the Krebs cycle process, electron transport chain functions, ATP synthesis, and the role of key molecules in energy production.

  1. WHAT HAPPENS NEXT? http://www.clickatutor.com/mitochondria.jpg

  2. Where will the NADH produced in this reaction go next if oxygen is present? Where will the pyruvic acid gonext if oxygen is present? To electron transport chain Into mitochondria and Krebs cycle

  3. Where does this reaction happen? Where will the pyruvic acid gonext if oxygen is NOT present? In the cytoplasm Stays in cytoplasm and does fermentation

  4. What happens to the CO2 produced in this reaction? Acetyl-CoA will join next with a 4 carbon molecule (OAA) to make __________ at start of Krebs cycle Released into atmosphere or used in photosynthesis Citric acid

  5. H+ H+ H+ H+ Which ion is being pumped across the membrane at the purple arrows during electron transport ?

  6. Where will the citric acid that is produced here go next? What will happen to the C’s in citric acid that came from Acetyl-CoA? Cycle through the Krebs cycle Released into atmosphere as CO2

  7. Where does the FADH2 produced here go next? Where does the ATP produced here go? to the Electron transport chain Used by cell for cellular activities

  8. What reaction happens on the matrix side of the membrane when ATP synthase spins? A phosphate is added to ADP to make ATP

  9. Name the 6 carbon molecule formed in this reaction What happens to the Coenzyme A after dropping off its 2 carbons? Citric acid Recycles back and picks up 2 more carbons from pyruvic acid

  10. Name the 4 products of the Krebs cycle CO2, NADH, FADH2, ATP

  11. Where does the CO2 produced here go next? released to the atmosphere or used in photosynthesis

  12. O2 Which molecule acts as the last electron acceptor to make water?
