1. Cellular Respiration Its how our cells release energy from food!
BrainPOP: Cellular Respiration

2. Do you remember??? What types of organisms do photosynthesis?
Why do plants do photosynthesis?
What are the reactants (what goes in)?
What are the products (what goes out)?
Which plant organelle is the site of photosynthesis?
How do animals get their energy?
How do they get food?
Which organelle releases energy from food?

3. Cellular Respiration energy
The process by which cells release from glucose (sugar).
energy
This process happens in BOTH
PLANT and ANIMAL cells!

4. Where do plants and animals obtain glucose?
FOOD!
Animals get it from the food they eat!
Plants get it from the food they make!

5. Glucose is the most common
sugar found in food!
C6H12O6

6. Besides glucose, what else do cells use for cellular respiration?
Oxygen
How do we get oxygen?
Breathing

7. energy
oxygen
food
breathing

8. Two Stages of Cellular Respiration
Use your
textbooks… page 382!
Two Stages of Cellular Respiration
Stage 1:
In the cytoplasm
Stage 2:
In the mitochondria
Glucose is broken down into smaller molecules
A small amount of energy is released
The smaller molecules react and produce carbon dioxide, water and large amounts of energy.

9. What are the reactants and products of cellular respiration?
C6H12O O CO H2O energy
glucose
oxygen
carbon dioxide
water
energy
Is matter conserved after this chemical reaction?

10. Cellular Respiration Equation
This energy is also known as ATP!
Reactants (what goes in)
Products (what comes out)

11. Compare and Contrast: Cellular Respiration & Photosynthesis
Reactants
Products
Organelle in which it occurs
Type of organism
light energy, CO2, H2O
glucose, O2
glucose, O2
energy, CO2, H2O
chloroplasts
mitochondria
producers such as plants and algae
both plants and animals

13. Create a Venn Diagram to compare and contrast Photosynthesis & Cellular Respiration
both

14. Exit Slip “P”= Photoysnthesis only “C”= Cellular respiration only
