Final answer:
Photosynthesis and cellular respiration are interconnected processes in living organisms that store and release energy. They also contribute to the recycling of oxygen in the atmosphere.
Step-by-step explanation:
What statement accurately compares the chemical processes of cellular respiration and photosynthesis? Among the given options, statement A. "Both processes use ATP as an energy carrier" accurately compares them. While photosynthesis makes the glucose that is used in cellular respiration to make ATP, cellular respiration breaks down glucose back into carbon dioxide, which is used in photosynthesis. These processes are interconnected; photosynthesis absorbs light energy to build carbohydrates and releases oxygen, while cellular respiration releases energy by using oxygen to metabolize carbohydrates and produces carbon dioxide and water. Both use electron transport chains in their pathways for making ATP, creating a cyclical exchange of matter and energy between them.
