Why does metabolism harvest energy in stages rather than all at once?
Diagram the major steps in each stage of cellular respiration.
Discuss the energy yield of aerobic respiration. How much energy is harvested at each step? What
form does that energy take? How does the energy yield differ in prokaryotes and eukaryotes and
why?
What are the key steps in the regulation of aerobic respiration?
Compare and contrast lactic acid fermentation and ethanol fermentation.
How does the cell harvest energy from other compounds besides sugars (e.g., proteins, fatty acids)?
Why does fat yield more energy than the same amount of sugar?
