1.

Jun Lee

Write the generalized reaction for aerobic respiration, utilizing the terms: ATP energy, water, carbon dioxide, carbohydrate and oxygen. Reactants Products Oxygen + C6H12O6 - H2O + CO2 + ((38)ATP)

2. Where in the cell, what organelle, does cellular respiration take place? - Mitochondria

3. In glycolysis, glucose is broken down to form two 3-carbon molecules called: -pyruvate (The next questions assume that you are starting with one molecule of glucose.) 4. What 2 places, organelles, in the cell are we discussing during cellular respiration (CR)? Cytoplasm and Mitochondira 5. When we are in the cytosol, is oxygen available? -No 6. When we are in the mitochondria is oxygen available? -Yes 7. When we start with one glucose molecule and end with 2 pyruvate, what reaction did we just complete? Glycolysis 8. In glycolysis, as glucose is oxidized, NAD is reduced 9. Does glycolysis require O2? -No 10. If a cell does not have a supply of O2, what process can it carry out after it has produced pyruvate acid? -Fermentation

11. If O2 is available, what reactions can occur after glycolysis? -Transition reaction 12. After the transition into oxygen, leaving you with 2Acetyl CoA, what is the next reaction? -Kreb Cycle OR citric acid cycle 13. What are the products of the Kreb Cycle? a. ATP b. CO2 c. FADH2 d. NADH 14. What are the 2 coenzymes that are converted to ATP with the electron transport chain, oxidative phosphorylation? -FADH2 and NADH 15. What happens to the NADH and the FADH coenzymes in the electron transport? a. Oxidized 16. The hydrogens removed from NADH and FADH 2 in electron transport are eventually combined with Oxygen to form Water...
