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
Leaves are flat, only a few cells thick, and expose a large surface area to the sun
CO2 from air enters leaf via adjustable pores, stomata, in epidermis

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. Types of Cellular respiration
Aerobic
Requires oxygen in order to take place
This process produces more energy
Anaerobic
Does not require oxygen to take place
Simple process that produces energy quickly

10. Comparing Photosynthesis and Cellular Respiration
Requires energy
Uses enzymes
Uses ETC
Gives off oxygen as waste
Requires carbon dioxide and water
Occurs in the chloroplast
Respiration
Requires energy
Uses enzymes
Uses ETC
Requires oxygen to breakdown sugars
Gives off carbon dioxide and water as waste
Occurs in the cytoplasm and the mitochondria.
