How do photosynthesis and cellular respiration differ?

• Photosynthesis uses food and cellular respiration produces food.
• Photosynthesis uses oxygen and cellular respiration uses carbon dioxide.
• Photosynthesis breaks down carbohydrates and cellular respiration produces carbohydrates.
• Photosynthesis gives off oxygen and cellular respiration uses oxygen.

What are the products of aerobic cellular respiration?

• glucose and water
• glucose and oxygen
• carbon, hydrogen, and water
• carbon dioxide, water, and energy

Which equation represents cellular respiration?
