1. Respiration Day 1

2. Saving for a Rainy Day
Suppose you earned extra money by having a job. At first, you might be tempted to spend all of the money, but then you decide to open a bank account.
What are the benefits of having a bank account?
What do you have to do if you need some of this money?
What might your body do when it has more energy than it needs?
What does your body do when it needs energy?

3. ENERGY ATP: Adenosine Triphosphate
Cell Respiration) - YouTube
ATP: Adenosine Triphosphate
Stores chemical energy released from cellular respiration
ATP releases energy for life processes by losing one phosphate, forming ADP (Adenosine Diphosphate)
Energy released from food is stored by adding a phosphate to ADP, forming ATP

5. Chemical Energy & Food
Calorie: energy needed to raise the temperature of 1 gram of water by 1 degree Celsius
Chemical energy stored in food (glucose) is released by breaking chemical bonds during cellular respiration

6. ATP / ADP Cycle

8. Respiration Day 2

11. Strongest Student Contest!
Let’s see who can hold piles of textbooks for the longest period of time!

12. Cellular Respiration
Brainpop

13. Cell Respiration
releases energy stored in the chemical bonds of food molecules, converting it to a useable form (ATP)
May or may not require oxygen (2 types)
occurs in the mitochondria and cytoplasm

14. 2 types of Cellular Respiration
Aerobic Respiration (OXYGEN required!)
Equation:
Yields a net gain of 36 ATP for each glucose molecule broken down
This energy is released a little at a time through a complicated set of reactions
Glycolysis (in cytoplasm)
Krebs Cycle
Electron Transport Chain
Glucose Song

16. Day 3
Anaerobic Respiration / Fermentation

17. 2) Anaerobic Respiration (a.k.a.Fermentation)
NO oxygen required
Produces only 2 ATP per glucose
Why do it????
Some types of cells lack the enzymes & organelles needed for aerobic respiration
When in short supply of oxygen, some animals will do it!

18. A. Lactic Acid Fermentation
Produces lactic acid and 2 ATP
Performed by animal cells and some bacteria
Associated with muscle fatigue
Important in production of cheese & yogurt

19. Equation:

20. B. Alcoholic Fermentation
Produces alcohol, CO2, and 2 ATP
Performed by yeast (fungi) & bacteria
(needed for baking, wine and beer making)

21. Equation:

22. 2 ATP O2 CO2 Lactic acid H2O C6H12O6 Alcohol (aka “fermentation)
Use these terms to complete the Respiration flowchart!
2 ATP O2
CO2
Lactic acid
H2O
C6H12O6
Alcohol
(aka “fermentation)
(uses oxygen)
~36 ATP

23. Day 4

27. SATII Material (Cristae) – Electron Transport Chain! (Inner Membrane)
Innermost section of the mitochondria (KREBS CYCLE!!)

29. Electron Transport System
2 molecules of pyruvic acid
NADH
4ATP (net gain 2ATP!!)
Anaerobic: uses no oxygen
All do it!
Glucose
2ATP for activation!
“breaking glucose”
Cytoplasm
CO2
8 NADH
2 FADH2
Matrix (“KR”)
Aerobic (needs O2)
Oxygen
2 Pyruvic Acids
Video
Cristae (inner membrane)
In some prokaryotes, occurs across the cell membrane
The most ATP!!!!! (34)
Water
Aerobic (needs O2)
(occurs in plants, animals, algae and some bacteria!)
NADH
FADH2
Oxygen (*final electron receptor!)
Electron Transport System

30. Evolved first!
Citric acid is constantly broken down and built up to produce high energy electron carriers!! (NADH and FADH2)
