Presentation Transcript

  1. Photosynthesis &Cellular Respiration So, how do living organisms get energy?

  2. Photosynthesis • Cells inside the kelp use energy from the sun to make glucose. • The kelp stores the glucose in its blades (like leaves).

  3. Cellular Respiration • Cells in fish use glucose from plants to make ATP or • ENERGY.

  4. Chemical Equation & Label Photosynthesis 6 CO2 + 6 H2O + Sunlight  C6H12O6 + 6 O2 Carbon Dioxide + Water + Energy  Glucose + Oxygen • Cellular Respiration C6H12O6 + 6 O2 6 CO2 + 6 H2O + 38 ATP Glucose + Oxygen  Carbon dioxide + Water + Energy

  5. Type Of Cell Photosynthesis Cells with chlorophyll (found in plants and plant-like organisms) • Cellular Respiration • All living cells, including plants MITOCHONDRIA

  6. Organelle Photosynthesis Chloroplasts • Cellular Respiration • Mitochondria

  7. When does it occur? Photosynthesis Daylight Hours • Cellular Respiration • At all times

  8. Reactants (what you start with) Photosynthesis Carbon dioxide Water • Cellular Respiration • Glucose (sugar) • Oxygen Oxygen

  9. Products (what you end with) Photosynthesis Glucose (sugar) • Cellular Respiration • Chemical energy = ATP Oxygen

  10. By-Products (Waste Products) Photosynthesis Oxygen • Cellular Respiration • Carbon dioxide • Water

  11. Type of Process Photosynthesis Constructive Glucose is built from smaller subunits • Cellular Respiration • Destructive • Glucose is broken down into smaller subunits

  12. What occurs? Photosynthesis Light energy is converted to chemical energy and stored in glucose • Cellular Respiration • Glucose is broken down to release energy
