Photosynthesis and Cellular Respiration Review

Photosynthesis and cellular respiration both involve the use and release of gases. Which statement correctly identifies the role of gases in the two processes?

• Photosynthesis and cellular respiration both use carbon dioxide and release oxygen.

• Photosynthesis and cellular respiration both use oxygen and release carbon dioxide.

• Cellular respiration uses oxygen and releases carbon dioxide, while photosynthesis uses carbon dioxide and releases oxygen.

• Cellular respiration uses carbon dioxide and releases oxygen, while photosynthesis uses oxygen and releases carbon dioxide.

What equation describes the process of cellular respiration?

• H2O + CO2 + Energy → C6H12O6 + H2O

• H2O + CO2 → C6H12O6 + O2 + Energy

• H2O + O2 + Energy → C6H12O6 + CO2

• O2 + C6H12O6 → H2O + CO2 + Energy
