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

Marisol has been chewing and swallowing her food, but her digestive system is not doing what it usually does. Why is this a problem for her ability to exercise?

• A Her cells will not work well because molecules from her food are not being broken down small enough to get to her cells.

• B Her body will run out of energy because molecules from the air are not being combined into larger molecules for the cells.

• C Her respiratory system will have to work twice as hard to break down molecules from food.

• D Her cells will not work well because the molecules from food will be too small for cells to use.
