1. Explain why photosynthesis is important to most ecosystems.

2. Define and compare autotrophs and heterotrophs, producers and consumers.

3. Explain how the processes of photosynthesis and cellular respiration are complementary to each other.

Explain how the processes of oxidation and reduction are used to transfer electrons from food molecules to NADH, the electron transport chain, and oxygen.

4. Compare the reactants, products, location in the cell, and energy yield of the three stages of cellular respiration (glycolysis, citric acid cycle, and electron transport chain).

5. Compare the reactants, products, and energy yield of aerobic metabolism versus fermentation in human cells. Indicate where this process occurs in each type of cell
