1. What two subunits made up ATP synthase? Explain what each subunit does.
2. This is a hypothetical situation. There is a mouse with a mutation that makes the F0 subunit of
ATP synthase less effective. In other words, the F0 subunit let protons go through without
efficiently turning its “fan.” This means the conversion of potential energy in the proton gradient
across the inner membrane to kinetic energy is less efficient. How does this mutant mouse look
like compared to the normal healthy mouse?
3. There are two types of anaerobic metabolism. Lactic acid fermentation occurs in
__________________ and ______________. Ethanol fermentation occurs in ______________
and _______________.
4. T/F Glucose is more efficient than fat.
5. One fatty acid molecule can produce a large number of ATP. Why?
6. Photosynthesis occurs in ___________________________.
7. The photosynthetic electron transport chain is in the ___________ ___________.
8. The Calvin cycle is in the ___________________.
9. Glycolysis takes place in the _______________. Glycolysis produces ____ pyruvate.
10. How can we trace oxygen atoms during photosynthesis?
11. What are the three steps of the Calvin cycle?
1.
2.
3.
10. What happens if cells don’t have oxygen available for cellular respiration?
11. What are the two common pathways of fermentation?
12. How is cellular preparation controlled? What inhibits and what stimulates?
13. What is the difference between substrate-level phosphorylation and oxidative
phosphorylation?
14. Fill in the table below.
15. Label the diagram below. [Word Bank: ATP Synthase, Complex I, Mitochondrial Matrix,
H +, Intermembrane space, Complex II, Complex III, ADP, ATP, P, Complex IV, NADH,
NAD+, FADH2, FAD, E-, O2, H20]
16. For cellular respiration, NADH enters complex _____ and FADH2 enters complex _____.
17. Which complexes pump protons? Do any complexes not pump protons?
18. Describe how a proton gradient is used to generate ATP.
