1. Standard 4- Metabolism (Cellular Respiration)
Biology1

2. The overall photosynthesis process: CO2 + H2O + light energy ---> C6H12O6 + O2
Light Independent Reaction (Calvin Cycle)
Light Dependent Reaction
Reactants (what we used):
H2O (Water)
Light Energy (Sun)
Products (what we gained):
ATP (energy)
NADPH (electron carrier)
02 (Oxygen)
Reactants (What we used):
ATP and NADPH (forms of energy)
C02 (Carbon Dioxide)
Products (What we gained):
Sugars (glucose)

3. Review Photosynthesis:
What are the environmental factors that affect the rate of Photosynthesis?
Temperature
Water
Light

4. Photosynthesis and Cellular Respiration relationship

5. Cellular Respiration Video

6. Overview of cellular respiration

7. What is Cellular Respiration?
Cellular Respiration is a process where cells transfer the stored energy in glucose into energy that can be released in ATP.

8. There are TWO types:
Type 1. Aerobic Respiration (with oxygen- it’s A LOT more efficient)
Type 2. Anaerobic Respiration (without oxygen)

10. Type 1. Aerobic Respiration
6O2 + C6H12O6  6CO2 + 6H2O + Energy ______ +_______ _______ +_______ + _____

11. Type 1: Aerobic Respiration
Respiration in the presence of O2
Glycolysis- breaks down glucose (in the cytoplasm)
Kreb’s Cycle- continues to break down pyruvate (in the mitochondria)- produces CO2
Electron Transport Chain- uses O2 to help make the majority of ATP and water (also in mitochondria)
2 ATP

18. Type 2: Anaerobic Respiration
Respiration in the Absence of O2
LESS efficient than aerobic respiration
Glycolysis is the first step!
Lactic Acid Fermentation
Lactic Acid is a by product
Lactic acid build-up causes muscle soreness
Produces 2 ATP OR
Ethanol Fermentation
Done by yeast and some bacteria
By products are CO2 and ethanol
Used for baking and brewing/winemaking
