1. Warm Up 11/13
Describe 5 ways in which photosynthesis is similar to cellular respiration.
What is the purpose of Oxygen in Aerobic Respiration?

2. Total Energy Production: 36 ATP
Aerobic Respiration
Total Energy Production: 36 ATP
2 ATP from glycolysis
2 ATP from Kreb’s Cycle
34 ATP from ETC (chemiosmosis)
38 ATP Made In Total
- 2 ATP for transporting pyruvic acid into the Mitochondria from Glycolysis
36 Net ATP Made
Aerobic Respiration is 20 times more efficient than Glycolysis alone.

3. Fact
Fact: Our bodies uses ATP at the rate of about 1 million molecules per cell per second.
There are more than 100 trillion cells in the human body. That’s about 100,000,000,000,000,000,000 ATP molecules used in your body each second!

4. Chapter 7: Cellular Respiration Fermentation
The Anaerobic Pathway
Chapter 7: Cellular Respiration Fermentation

5. Fermentation Fermentation = Glycolysis + Anaerobic pathway
Occurs when there is no oxygen present
Occurs in the cytoplasm

6. Two types of Fermentation
Lactic Acid Fermentation
Alcoholic Fermentation

7. Example #1: Lactic Acid Fermentation
Anaerobic Pathway
Example #1: Lactic Acid Fermentation
● Pyruvic Acid from glycolysis is converted into another 3 carbon compound, Lactic Acid
● The process uses NADH converting it into NAD+
● Muscle cells may produce Lactic Acid during strenuous exercise causing fatigue and pain
● Certain Bacteria and Fungi are used to ferment milk into cheese, buttermilk, yogurt, sour cream and other cultured dairy goods.

8. Example #2: Alcoholic Fermentation
Anaerobic Pathway
Example #2: Alcoholic Fermentation
Pyruvic Acid is converted into ethyl alcohol and CO2
The process uses NADH converting it into NAD+
NAD+ is then used to power glycolysis

9. Example #2: Alcoholic Fermentation
Anaerobic Pathway
Example #2: Alcoholic Fermentation
Performed by plant cells and unicellular organisms like Yeast
This process is also used in Bread-making
CO2 makes the bread rise & the alcohol evaporates during cooking
The Alcohol Industry uses
this process to make different beverages
● If the CO2 is allowed to escape = wine
● If the CO2 is kept in the liquid = sparkling wines or champagne

10. Fermentation vs. Cellular (aerobic) Respiration
Fermentation = Glycolysis + Anaerobic pathway
● Cellular (aerobic) Respiration = Glycolysis + Aerobic pathway
● produces 2 net ATP (from glycolysis)
● produces 36 more ATP
● recycles NADH made in Glycolysis into NAD+
●Kreb’s Cycle makes energy to power ETC
● Recycled NAD+ keeps Glycolysis going
●ETC uses chemiosmosis to make ATP
● Occurs in the cytoplasm
● Occurs in the mitochondria
● Goal: keep Glycolysis going in order to make 2 ATP
● Goal: Make a lot of ATP!
