Question 11 Photosynthesis and cellular respiration both include water in their summary reactions . Which statement correctly identifies the role of water in these two processes ? Cellular respiration uses oxygen and releases water, while photosynthesis uses water and releases oxygen Photosynthesis and cellular respiration both use oxygen and release water Photosynthesis and cellular respiration both use water to help release oxygen Cellular respiration uses water and releases oxygen, while photosynthesis uses oxygen and releases water

Answer 1

The correct statement is: Cellular respiration uses oxygen and releases water, while photosynthesis uses water and releases oxygen.

In summary:

• Photosynthesis (6CO2 + 6H2O -> C6H12O6 + 6O2) uses water and carbon dioxide to produce glucose and releases oxygen.
• Cellular respiration (C6H12O6 + 6O2 -> 6CO2 + 6H2O) uses glucose and oxygen to produce carbon dioxide, water, and energy (ATP).
