- 15. Multiple ChoiceIn 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 used carbon dioxide, while cellular respiration produces carbon dioxide.
- 16. Multiple ChoiceWhich of the following structure is where cellular respiration occurs in the cell?nucleuscytoplasmmitochondriavacuoles
- 17. Multiple Choice
What is the correct equation for cellular respiration?
6O2 + C6H12O6 -> 6CO2 + 6H2O + Energy
