NAME ___________________________ Bio 311C F08 Discussion Worksheet #10 Cellular Respiration 1. What is oxidation? Reduction? 2. What is a reducing agent? An oxidizing agent? 3. What is substrate-level phosphorylation? During which phases of cellular respiration does substrate-level phosphorylation occur? 4. 4 molecules of ATP are made during glycolysis. Why is the net yield for glycolysis only 2 molecules of ATP? 5. Glycolysis occurs in the cytosol while the final two stages of cellular respiration occur in the mitochondrion. Where in the mitochondrion do the final two stages occur? 6. During glycolysis, 1 molecule of glucose is broken down to 2 molecules of what? 7. What determines if the product of glycolysis will be used for fermentation or cellular respiration? 8. Before the citric acid cycle can begin, the 3C product of glycolysis must first be converted to what?

Unformatted text preview: What is released as a waste product? 9. The complete oxidation of 1 molecule of pyruvate results in the formation of how many NADH + H+? How many FADH2? 10. The complete oxidation of 1 molecule of glucose results in the formation of how many NADH + H+? How many FADH2? 11. NADH and FADH 2 both transfer electrons to the electron transport chain. Why does the release of electrons from NADH to the ETC result in the production of more ATP than the release of electrons from FADH 2 ? 12. The complete oxidation of 1 molecule of glucose results in the formation of how many molecules of ATP via oxidative phosphorylation? Why is this number not exact? 13. What is fermentation? 14. What are the two main types of fermentation? How are they similar? How do they differ? 15. How is ATP produced by oxidative phosphorylation?...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
