In which way are photosynthesis and cellular respiration different?

• Cellular respiration stores ATP, while photosynthesis releases ATP.

• Cellular respiration produces oxygen, while photosynthesis uses oxygen.

• Photosynthesis releases energy, while cellular respiration stores energy.

• Photosynthesis uses carbon dioxide, while cellular respiration produces carbon dioxide.

What is the correct equation for cellular respiration?

• 6O₂ + C₆H₁₂O₆ -> 6CO₂ + 6H₂O + Energy

• 6O₂ + C₆H₁₂O₆ + Energy -> 6CO₂ + 6H₂O

• 6CO₂ + 6H₂O -> 6O₂ + C₆H₁₂O₆ + Energy

• 6CO₂ + 6H₂O + Energy -> 6O₂ + C₆H₁₂O₆
