Photosynthesis &
Cellular Respiration
The process by which energy from the sun is used to
convert carbon dioxide and water into glucose and
oxygen
Photosynthesis
Photosynthesis Con’t• Photosynthesis occurs in algae,
certain types of prokaryotes, and the chloroplasts of eukaryotic plants
• Structure and shape of a leaf is adapted for photosynthesis
Chemical Equation of Photosynthesis
6CO2 + 6H2O + Energy C6H12O6 + 6O2(Light)
The process by which the stored energy in glucose molecules is broken down to release ATP.
Cellular Respiration
Chemical Equation of Cellular Respiration
C6H12O6 + 6O2 6CO2 + 6H2O + Energy(ATP)
Cellular Respiration Con’t
Cellular respiration occurs in all eukaryotic organisms
Begins in the cytoplasm, but is completed in the mitochondria
Produces ATP for the cell Remember ATP is the only usable form of energy for
the cell
Cellular Respiration is NOT:
Breathing
Exchange of gases with the atmosphere
The transport of oxygen and carbon dioxide to/from the cell.
Comparing Photosynthesis and Cellular Respiration
Photosynthesis Requires energy Uses enzymes Gives off oxygen as
waste Requires carbon
dioxide and water Occurs in the
chloroplast
Respiration Requires energy Uses enzymes Requires oxygen to
breakdown sugars Gives off carbon
dioxide and water as waste
Occurs in the cytoplasm and the mitochondria.
