2. Goal Equation of Cell. Resp.
How Cellular resp. relates to photosynthesis.
Difference between Aerobic & Anaerobic Resp.

3. Photosynthesis occurs in the Chloroplast Cellular Respiration occurs in the Mitochondria

4. BOTH Plants & animals use cellular respiration

5. Cellular Respiration
A process done in mitochondria of cells, with or without oxygen, in which organisms break down food to release energy (ATP)
CO2 + H2O + heat
fuel (carbohydrates) O2
You burn fuel in many small steps
Movement of hydrogen atoms from glucose to water
ATP
food (carbohydrates) O2
ATP + CO2 + H2O (+ heat)

6. The purpose of Cellular Respiration is to create ENERGY in the form of ATP!
Whoa! HOT stuff!

7. Two Types of Cellular Respiration
Aerobic Respiration

10. 3 Steps for Aerobic Respiration
Gycolysis – cuts glucose into two pyruvate
Occurs in cytoplasm of cell
“cuts” glucose into 2 pyruvate
Creates 2 ATP & NADH
Kreb Cycle
In mitochondria’s matrix
Purpose is to create Hydrogen carrying vehicles; NADH and FADH2
And creates 2 ATP, and CO2

food O2

11. 3 Steps for Aerobic Respiration
Electron Transport Chain
Occurs in cristae (folds)
Oxygen taken in
And pulls Hydrogen off of NADH, FADH2 which turns an ATP protein channel
Creating ATP and Water (H2O)

13. Tastes good… but not enough energy for me!
Types of Anaerobic Respiration
Yeast = alcohol fermentation
make beer, wine, bread
Bacteria/Animals= lactic acid fermentation
Bacteria (eat milk) make yogurt
animals feel muscle fatigue O2
How it’s made: Beer
After heating the milk, they quickly reduce the temperature to about 112 degrees (44 degrees Celsius).
Next comes the bacteria! This might sound gross, but these kinds of bacteria are not the kinds that make you sick. The bacteria used in yogurt actually give it a tangy flavor.
The species of bacteria used in yogurt are Streptococcus thermophilus and Lactobacillus bulgaricus. These species eat the sugars in milk. As the bacteria eat milk sugars, the bacteria produce something called lactic acid. Lactic acid makes milk proteins curdle. Thanks to the bacteria, the milk becomes thick yogurt. The lactic acid also gives yogurt a tart, tangy flavor.
As an added bonus, most harmful bacteria can’t survive around high levels of lactic acid. That means the bacteria that give yogurt its tangy flavor can also keep yogurt safe to eat.
Tastes good… but not enough energy for me!

14. 2 Steps of Anaerobic Respiration
ATP
food
Glycolysis
Occurs in cytoplasm of cell
creates 2 ATP, 2 pyruvate
Fermentation
Also occurs in cytoplasm
Pyruvate Creates alcohol (yeast) OR Lactic Acid (animal/Bact.) O2
glucose  ATP + CO2+ alcohol
glucose  ATP + lactic acid
Yeast

19. Critical Questions: 1. What are the reactants and products of Cellular Respiration? 2. How Do they relate to the reactants and products of Photosynthesis?

20. Mitochondria
Mitochondria is composed of inner and outer membranes. The inner membrane is folded in forming cristae. The matrix, a gel like fluid, fills the inner membrane.
Locations of Aerobic Cellular Respiration:
Glycolysis – cytoplasm of cell
Kreb’s cycle – matrix of mitochondria
ETC – inner membrane wall of mitochondria
Locations of Anaerobic Cellular Respiration:
Fermentation – cytoplasm of cell

21. Overall Process’ Goal is to make ATP
Digestion! (biomolecules transported into blood stream and into surrounded tissue cells)
Cellular Respiration Steps: 3 stages
Glycolysis (2 phases) in cytoplasm
Energy investment phase – 2 ATP
Splits 6 carbon molecules into two 3 carbon molecules
Energy harvesting phase
Glycolysis creates – 2 ATP Molecules
2 Pyruvate & 2 NADH
pyruvate
NADH

24. Different energy outputs for different Biomolecules
Fat produces 80 percent of the energy in your body
about 146 ATP (energy molecules) from a triglyceride
Proteins are least likely to be broken down to make ATP.
amino acids not usually needed for energy
about the same amount of energy as a carbohydrate

25. Some organisms live in places that never get sunlight.
A few types of organisms do not need sunlight and photosynthesis as a source of energy.
Some organisms live in places that never get sunlight.
In chemosynthesis, chemical energy is used to build carbon-based molecules.
similar to photosynthesis
uses chemical energy instead of light energy

26. O2 Anaerobic respiration no oxygen or NO mitochondria
Also known as fermentation
Bacteria/Yeast use anaerobic
No mitochondria (prokaryotic)

27. Used for -synthesis (building) -reproducing
-active transport -movement
-Temp. control (making heat)
Which is to say… if you don’t eat, you die… because you run out of energy.
