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

Answer 1

The correct statement is:

b Cellular respiration uses oxygen and releases water, while photosynthesis uses water and releases oxygen.

In photosynthesis, water is utilized along with carbon dioxide to produce glucose and oxygen, while in cellular respiration, glucose (along with oxygen) is broken down to produce energy, carbon dioxide, and water.
