Photosynthesis
Photosynthesis Equation
6 CO2 + 6 H2O  C6H12O6 + 6 O2
Carbon Dioxide + Water  Glucose + Oxygen
IMPORTANT FACTS
1. Plants make their own food through
Photosynthesis
2. Plants = Autotroph
3. Photosynthesis occurs in the Chloroplast
The Chloroplast
A)
B)
C)
IMPORTANT FACTS
4. The major pigment for photosynthesis is
Chlorophyll
5. Chlorophyll is found in the Thylakoids of the
chloroplast
6. Step of photosynthesis that happens in the
Thylakoids = Light Dependent Reactions
a. Splits Water (H2O) into Oxygen (O2)
b. Stores Energy for next step (ATP & electron carriers)
7. Step of photosynthesis that happens in the
Stroma = Calvin Cycle
a. Uses Carbon Dioxide & Hydrogen to make Glucose

Cellular Respiration
Cellular Respiration Equation
C6H12O6 + 6 O2  6 CO2 + 6 H2O + 36 ATP
Glucose + Oxygen  Carbon Dioxide + Water + Energy
IMPORTANT FACTS
1. The process of making energy by breaking down
sugars is called Cellular Respiration
2. ALL Eukaryotes (plants, animals, fungi, &
protists) perform cellular respiration
3. Animals & Fungi = Heterotrophs
Mitochondria & Cellular Respiration
A)
B)
C)
4. MUST have Oxygen =
aerobic
5. NO oxygen needed =
Anaerobic
6. Aerobic Cellular
Respiration occurs in
the Mitochondria of
cells
D) Mitochondrion
IMPORTANT FACTS
7. 1st step = Glycolysis (anaerobic)
a) Occurs in Cytoplasm
b) # of ATP produced = Net gain of 2 + electron carriers
8. 2nd step = Krebs Cycle (aerobic)
a) Occurs in Matrix of Mitochondria
b) # of ATP produced = 2 + electron carriers
9. 3rd step = Electron Transport Chain (aerobic)
a) Occurs in Inner Membrane of Mitochondria
b) # of ATP produced = 32 ATP
IMPORTANT FACTS
10.Total # of ATP produced = 36 (2 + 2 + 32)
11.If no oxygen is available after glycolysis, cells
go through Fermentation instead of Krebs
Cycle & ETC (electron transport chain)
