During cellular respiration, energy is released from food. What else does the cell need for this process to take place.
carbon dioxide
oxygen
sunlight
nitrogen
Most energy that is released during respiration is produced in the ____

chloroplast
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 glucose, while cellular respiration stores glucose.
Photosynthesis uses carbon dioxide, while cellular respiration produces carbon dioxide.
What is the correct equation for cellular respiration?
6O2 + C6H12O6 -> 6CO2 + 6H2O + ATP
6O2 + C6H12O6 + ATP -> 6CO2 + 6H2O
6CO2 + 6H2O -> 6O2 + C6H12O6 + ATP
6CO2 + 6H2O + ATP -> 6O2 + C6H12O6

only autotrophs
both autotrophs and heterotrophs
only heterotrophs
