4. Photosynthesis and cellular respiration can be considered opposite processes because:

• Photosynthesis releases oxygen, while cellular respiration uses oxygen.

• Both processes occur in the mitochondria.

• Photosynthesis and cellular respiration both produce glucose.

• Both processes require sunlight.

5. In what ways do aerobic respiration and anaerobic respiration differ?

• Aerobic respiration requires oxygen, while anaerobic respiration does not.

• Anaerobic respiration produces more energy than aerobic respiration.

• Both processes occur in the mitochondria.

• Aerobic respiration occurs only in plants.
