1. Photosynthesis vs. Cellular Respiration

2. Photosynthesis Occurs in chloroplasts of plants
What do plants need in order to grow?
Water
Sunlight
Carbon dioxide
What is produced as a waste product?
Oxygen
What is a product that plants use as food?
Glucose

3. Chloroplast Structure
Inner membrane called the thylakoid membrane.
Thickened regions called thylakoids. A stack of thylakoids is called a granum. (Plural – grana)
Stroma is a liquid surrounding the thylakoids.

4. Photosynthesis Formula
6Co2 + 6H2O  C6H12O6 + 6O2

5. Cellular Respiration Takes place in the cytoplasm and mitochondria
3 Main steps
Glycolysis – occurs in the cytoplasm
Makes 2 ATP
Krebs Cycle – occurs in the mitochondria
Electron Transport Chain – occurs in the mitochondria
Makes 34 ATP

6. Cellular Respiration Equation
C6H12O6 + 6O2  6Co2 + 6H2O + Energy

7. Comparing energy flow Cellular Respiration Photosynthesis Cytoplasm
Occurs in what organelle
Cytoplasm
Mitochondria
Chloroplast
Reactants
C6H12O6 and O2
CO2 and H2O
