3. Review What’s the purpose of Photosynthesis?
What’s the final product of Photosynthesis?

4. What is Cellular Respiration?
The process of converting sugar (Glucose) into energy (ATP).
Overall equation:
C6H12O6 + 6O2 —> 6CO2 + 6H2O + Energy (ATP)
Glucose + Oxygen —> Carbon Dioxide + Water + Energy
What’s the equation for Photosynthesis?

5. Anaerobic Respiration
2 Types
Anaerobic Respiration
Does NOT require Oxygen
Produces 2 ATP
Occurs in cytoplasm.
Aerobic Respiration
Requires Oxygen
Produces 36 ATP
Occurs in eukaryotic cells’ mitochondria and cytoplasm.

6. 3 Stages Glycolysis What does this word mean? The Krebs Cycle
Electron Transport Chain

8. 1. Glycolysis Glyco (Sugar) + Lysis (Break Down)
Occurs in the cytoplasm
Split Glucose up into 2 molecules of Pyruvic Acid
Makes 2 ATP
Uses up 2 ATP, but makes 4 ATP = 2 ATP
Sends off electrons ****More on this later.

9. 2. The Krebs Cycle Occurs in the mitochondrial matrix.
Takes and breaks down Pyruvic acid from Glycolysis, and produces Carbon Dioxide (CO2).
Makes 2 ATP
Sends off electrons

13. Electron Carriers are like busses.
2 Types
NADH
FADH2
They carry electrons to the electron transport chain, which will be used to make ATP.

14. 3. Electron Transport Chain
Occurs in the intermembrane space (cristae) of mitochondrion.
Starts with electrons (which build up inside the matrix)
Requires Oxygen
Produces Water
Produces 32 ATP

17. Summary Glycolysis Krebs Cycle ETC Occurs in cytoplasm
Makes net of 2 ATP
Occurs in Mitochondria
Makes 2 ATP
Makes 32 ATP

19. Review
Cellular respiration is called aerobic, because it requires what?
How many ATP does Glycolysis produce?
Where does Glycolysis take place?
What’s the purpose of electron carriers?
What’s a waste product of cellular respiration?
What’s the overall equation for cellular respiration?

20. Anaerobic Respiration
2 Types
Anaerobic Respiration
Does NOT require Oxygen
Produces 2 ATP
Occurs in cytoplasm.
Aerobic Respiration
Requires Oxygen
Produces 36 ATP
Occurs in eukaryotic cells’ mitochondria and cytoplasm.

21. 2 Types of Anaerobic Respiration
Alcoholic Fermentation
Starts with Glycolysis
Occurs in yeast, plants, and other one-celled organisms.
Produces 2 ATP and ethyl alcohol
Lactic Acid Fermentation
Starts with Glycolysis
Occurs in animal muscle cells and some one-celled organisms.
Produces 2 ATP and Lactic Acid
Produces soreness when it builds up in your muscles.

25. Occurs Where? Cytoplasm -> Glycolysis
Mitochondria -> Matrix (The Krebs Cycle)
-> Intermembrane Space (ETC)

26. Glycolysis Occurs in Cytoplasm Splits Glucose
Makes 2 molecules of Pyruvic Acid
Makes 2 ATP
Sends off electrons

27. The Krebs Cycle Occurs in the Mitochondrial Matrix
Breaks down pyruvic acid and produces CO2
Makes 2 ATP
Sends off electrons

28. Electron Transport Chain
Occurs in the intermembrane space (cristae) of mitochondria
Starts with electrons
Requires oxygen
Produces water
Makes 32 ATP

29. Reactants
Sugar (Glucose)
Oxygen

30. Products
Water (H2O)
Carbon Dioxide (CO2)
Energy (ATP)

31. Overall Equation
C6H12O6 + 6O2 —> 6CO2 + 6H2O + Energy (ATP)
