Does photosynthesis absorb or release energy?
What types of cells carry out photo?
Big Goal?

2. Photosynthesis & Cellular Respiration
EQ: How is energy acquired and used by organisms?

3. Making connections with Claudel and the family
Basic Bubba
Claudel the Cell
Penny the Plant Cell
Making connections with Claudel and the family
What do we know about Claudel and the cousins so far?
What do all three cousins have in common?
How are Claudel and Penny different from Bubba?
How do Claudel and Penny use the following macromolecules?
Carbohydrates, Lipids, Proteins, & Nucleic Acids?
Why is DNA replication important to Claudel and Penny?
Where do these cells get the energy to perform all cellular activities ?

4. What is photosynthesis?
Sun
Light
Oxygen
Gas that exits through the stomata of the leaves
Chlorophyll inside of Chloroplast
Carbon Dioxide
Gas that enters through the stomata of the leaves
Trap light energy to make food (sugars)
Sugar
Photo= light
Synthesis = build
Water
Converted to starch and stored in the plant vacuole as food
Absorbed from the roots -
Capillary action

5. Photo Review Where does it occur? Purpose? Equation:
sun
CO2
Photo Review
Where does it occur?
Chloroplast (plants cells)
Purpose?
Make food for the plant
Equation:
6CO2 + 6H2O +sun C6H12O6 + 6O2
SUGAR &
Oxygen

7. Cellular Respiration
Identify the reactants, products, and basic function of aerobic and anaerobic respiration.
Lets investigate!

8. What’s happening? Ingredients: Predictions? Warm water Yeast Sugar
Is yeast alive?
Where does it
get energy?

9. Key Point #1
All living organisms need energy to carry out the processes of life.

10. What do we need energy for?
synthesis (building for growth)
reproduction
active transport
movement
temperature control (making heat)
Which is to say… if you don’t eat, you die… because you run out of energy.
The 2nd Law of Thermodynamics takes over!

11. Think-Pair-Share Where do we get our energy from?
What is in our foods that we need that we use for energy?

12. Where do we get energy? Energy is stored in organic molecules
carbohydrates, lipids, proteins
Animals are energy consumers, they eat these organic molecules in their food
digest food to get fuels for energy (ATP)
We eat to take in the fuels to make ATP which will then be used to help us build biomolecules and grow and move and… live!
heterotrophs = “fed by others”
vs.
autotrophs = “self-feeders”

13. Stop and think:
What organelle in Eukaryotic cells are responsible for making energy?

14. Mitochondria are everywhere!!
animal cells
plant cells
Both plants and animals have mitochondria!

15. ATP What is ATP? ATP= Adenosine TriPhosphate ATP is cellular energy
Without ATP, our cells cant function
Recall: cells tissue  organs ….
ATP

16. How do our cells make energy?
Cellular respiration: a chemical reaction the breaks down sugar (food) to produce ATP
Occurs in mitochondria
Requires oxygen
Aerobic respiration
Respiration release
energy the cell can use
Movement of hydrogen atoms from glucose to water
Label the mitochondria in your notes!

17. Stop and think
CR is a chemical reaction, what are the two parts of a chemical reaction?
What are the catalyst in living things that helps speed up the rate of reaction?

18. Cellular Respiration Equation
C6H12O6
6O2
ATP
6CO2
6H2O  +
glucose + oxygen  energy + carbon + water
dioxide
Reactants? Products?
Box them! Circle them!

19. What if oxygen is missing?
No oxygen available aerobic respiration
Without oxygen, the reaction Becomes Anaerobic Respiration
aka Fermentation
Produce very little amount of ATP O2

20. Anaerobic Respiration
AKA Fermentation
Two types:
Alcohol fermentation
Yeast; make beer, wine, bread
glucose  ATP + CO2+ alcohol
Lactic acid fermentation
bacteria make yogurt
animals feel muscle fatigue
glucose  ATP + lactic acid
When would the mito not be present? What type of cell?
- prokaryotic still living, still need energy, just not as much O2

21. When you breath, you inspire. When you do not breath, you expire!
Ha!
When you breath, you inspire. When you do not breath, you expire!

22. Got the energy… Ask Questions!!
Wait!
What about
the balloon?

23. What’s happening? Ingredients: How is the balloon expanding?
Warm water, yeast & sugar
How is the balloon
expanding?
Is this aerobic or anaerobic respiration?
What were the products
and reactants?
glucose  ATP + CO2+ alcohol
