Texts:
1. What are the 3 parts of chemiosmosis and what does each of them do?
2. Some athletes don't want to wait for natural (natty) muscle gains and take anabolic steroids. Why are these steroids called "anabolic?"
3. A moon of Jupiter, Europa, has a thick icy surface. Under this surface, there is liquid water and chemical energy. Could anything live there? Why or why not?
4. Single-celled organisms in the genus Euglena can get their energy from sunlight during the day but will eat other organisms for energy at night. How would you classify this organism nutritionally?
5. In detail, what makes NADH different from NAD+?
6. During aerobic cellular respiration, which step or steps require oxygen?
7. If you don't eat sugar, your body will make sugar from protein or fat. What is in our cells that gives us this ability?
8. What is my nutritional classification if I get my energy from the sun, my electrons from organic sources, and my reduced carbon from CO2?
9. If a cell has plenty of oxygen, would it ever do fermentation? Why or why not?
10. If I am an RNA virus, do I need ATP? Why or why not?
11. What are the 3 things that all cells need?
12. Deep under the ocean where there is no sunlight, there are heterotrophs. Do these heterotrophs need autotrophs? Why or why not?
13. How does a photoorganoautotroph solve its 3 nutritional needs?
14. When carbon or nitrogen is "fixed," what is chemically happening to these atoms?
15. If I have a functional electron transport chain, why would I ever do fermentation?
16. Besides connecting glycolysis to the citric acid cycle, why is Acetyl-CoA considered to be an intermediate molecule in metabolism?
17. Do photolithoheterotrophs perform photosynthesis? Why or why not?
18. We spent lecture 6 talking about glucose catabolism. What other molecules can be catabolized?
19. Potential free space. A roll of 19 is re-rolled and, if it is >18 this is a free space. Rolls <18 must be answered like a normal roll.
20. Free space. If I roll a 20, you don't have to answer a question and get full credit.
Challenge Question:
21. What are NAD and FAD? In which metabolic processes are they involved?
22. What is the biochemical difference between anaerobic respiration, aerobic respiration, and fermentation?
