Presentation Transcript

  1. Photosynthesis & Cellular Respiration

  2. Photosynthesis The process by which energy from the sun is used to convert carbon dioxide and water into glucose and oxygen

  3. 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

  4. Chemical Equation of Photosynthesis 6CO2 + 6H2O + Energy  C6H12O6 + 6O2 (Light)

  5. Cellular Respiration The process by which the stored energy in glucose molecules is broken down to release ATP.

  6. Chemical Equation of Cellular Respiration C6H12O6 + 6O2 6CO2 + 6H2O + Energy (ATP)

  7. 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

  8. Cellular Respiration is NOT: • Breathing • Exchange of gases with the atmosphere • The transport of oxygen and carbon dioxide to/from the cell.

  9. 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.
