1. Cellular
Respiration

2. What is Cellular Respiration?
This process is the opposite of photosynthesis
Plants take in CO2 to produce O2 and energy
Animals take in (breathe) O2, and with the use of energy, produce CO2

3. Equation for Cellular Respiration

4. Photosynthesis Equation

6. Processes of Cellular Respiration
I. Glycolysis
Occurs in cytoplasm
Breaks down glucose and produces 2 ATP

7. Processes of Cellular Respiration
II. Kreb’s Cycle
Occurs in mitochondria
Continues breakdown of glucose and produces 2 ATP

8. Processes of Cellular Respiration
III. Electron Transport Chain
Occurs in mitochondria
Finishes breakdown of glucose, grabs electrons and passes them along a chain of molecules
32 ATP made

9. Types of Respiration 1. Aerobic Respiration – requires oxygen
2. Anaerobic Respiration – does not require oxygen

10. Two Types: 2 ATP Made!! Lactic Acid Fermentation
In cytoplasm of human cells (working muscles) when oxygen (O2) is lacking
Glucose is partially broken down into lactic acid
Lactic acid builds up and causes sore muscles
2 ATP Made!!

11. 2 ATP made!!! Two Types: Alcoholic Fermentation In cytoplasm of yeast
Glucose is partially broken down to alcohol
This is how beer, wine, etc. is made
2 ATP made!!!

13. Talk to your plants!!!

14. Together,
with plants,
we maintain
homeostasis!

17. Additional Notes:
Cellular Respiration
Includes all chemical reactions that provide energy for life
Carbohydrates are primary energy source
ATP = Adenosine Triphosphate
“battery” – energy for chemical reactions
