Photosynthesis & Cellular Respiration

• Comparing Photosynthesis and Cellular Respiration

  • Opposite flow of energy
  • Photosynthesis stores energy in glucose
  • 6CO2 + 6H2O -> C6H12O6 + 6O2
  • Cellular respiration releases the energy from sugars as free energy (ATP)
  • C6H12O6 + 6O2 -> 6CO2 + 6H2O + ATP
  • The products of one reaction are the reactants of the other
  • Photosynthesis removes carbon dioxide and CR puts it back into the atmosphere
  • CR removes oxygen and photosynthesis puts it back into the atmosphere
  • Both plant and animals cells preform CR, but only plants preform photosynthesis
