1. Cellular Respiration and Photosynthesis
“biochemical pathways”

2. Classification of Organisms
Autotrophs
- makes glucose (producers)
- plants
- give us food
Heterotrophs
- obtain glucose (consumers)
- animals
- depend on autotrophs for glucose

3. Cellular Respiration “heterotrophs”
Equation
Occurs in mitochondria
Two types
a. aerobic respiration
b. anaerobic respiration

4. Aerobic Respiration
“uses oxygen”
Makes the MOST ATP (32-38)

5. Anaerobic Respiration
“no oxygen”
Makes 2 ATP
Lactic acid fermentation
Alcohol fermentation

6. Photosynthesis “autotrophs”
Equation
Occurs in chloroplast
Ultimate source of energy: sunlight

7. Two phases in Photosynthesis
1. light dependent
a. depends on light
b. water and ADP yields oxygen and
ATP
2. light independent
a. depends on CO2
b. uses the ATP
and CO2 to make glucose

8. Biochemical Pathways
The reactants of one equation are the products of the other; each are dependent on one another
