1. Review
Photosynthesis

2. Respiration

3. ?Why do you breathe? To release energy!
Just like a fire needs oxygen to burn, our cells need oxygen to “burn” the sugar in our cells
To release energy!

4. Cellular Respiration
The process where cells obtain glucose from food and break it down to release energy
Energy!
The opposite of photosynthesis

5. Reactants
Products
Glucose
Carbon Dioxide
Water
Oxygen
Energy (ATP)

6. 6CO2 + 6H20 C6H1206 + 6O2 Respiration Equation Reactants Products
Energy!
C6H O CO H20 + Energy
(ATP)
Notice anything?
It’s the flip of photosynthesis…..
6CO2 + 6H C6H O2
Sunlight (energy)

7. Powerhouse? Aerobic Respiration takes place in the mitochondria
Similar to the chloroplast the Mitochondria has membranes that are folded to allow for more surface area for chemical reactions.
Anaerobic Respiration takes place in the cell’s cytoplasm

8. This is the cells way of storing and using energy
ATP
ATP- Adenosine Triphosphate
ADP- Adenosine Diphosphate
It’s a Nucleotide
Phosphate
Sugar
Base

9. ADP
ATP

10. ATP/ADP cycle
ENERGY!
All of the energy is stored between the 2nd and the 3rd phosphate of ATP

11. ATP/ADP cycle To release energy break off the 3rd phosphate
To store energy add a 3rd phosphate

12. ATP/ADP cycle

13. ATP/ADP cycle

ADP=
Used battery
Recharged battery

14. ATP/ADP cycle

Used battery
Recharged battery

15. Who does respiration? When does it happen? All the time
Every living thing
When does it happen?
All the time

16. There are two types of Respiration
Aerobic
With oxygen
This make a lot of energy
Feel the Energy!!! YEAAA!
36 ATP

17. Makes your muscles sore!
No oxygen
Anaerobic Respiration
I’m so tired!
Also called Fermentation
Only Makes 2 ATP
Alcohol Fermentation
Yeast
Ouch!
Makes your muscles sore!
Lactic Acid Fermentation
Bacteria and Muscles

18. Which organisms do this?
Respiration
Photosynthesis
Reactants
Products
Which organisms do this?
Where in the cell does this happen?
Carbon Dioxide
Water
Light
Glucose
Oxygen
Carbon Dioxide
Water
Energy (ATP)
Glucose
Oxygen
Producers (Plants)
Every living thing
Chloroplast
Mitochondria or Cytoplasm
