Unit 4: Bioenergetics

Major Topics in this Unit:

• ATP and ADP

• Aerobic vs Anaerobic Respiration

• Cellular Respiration

• Autotrophs vs Heterotroph

• Photosynthesis

• Nutrient Cycles

Essential Questions:

1. How does cellular respiration create energy for the cell?

2. How do the products and reactants of each step in cellular respiration relate to the other steps?

3. How does the cell determine which pathway to take after glycolysis during cellular respiration?

4. How do plastids, like mitochondria and chloroplast, help with cellular respiration and photosynthesis?

5. How can the rates of cellular respiration and photosynthesis be altered?

6. How does ATP drive chemical reactions?
