Which of the following best describes the relationship between photosynthesis and cellular respiration?

• Photosynthesis releases oxygen, which is used in cellular respiration to produce ATP.

• Cellular respiration produces glucose, which is used in photosynthesis.

• Photosynthesis and cellular respiration are identical processes.

• Both processes store energy in the form of ATP.

• Cellular respiration does not require oxygen, unlike photosynthesis.
