3. Photosynthesis vs Cell Respiration What similarities do you see?

4. Chemical Energy and Food
PHOTOSYNTHESIS
___________ + _________ + ___________ →_______________ + __________
6 CO2
6 H2O
C6H12O6
6O2
CELLULAR RESPIRATION
C6H12O6
6 CO2
_____________ + _________ →________ + __________ + __________
6O2
6 H2O
The two equations are exact opposites!

5. Uses of ATP Powers protein pumps in the cell membrane
Powers cilia and flagella
Power for synthesis of proteins
Powers motor proteins that contract muscles
Provides cell energy

6. Cell Respiration 3 Major Steps GLYCOLYSIS: break glucose in ½
KREBS CYCLE: keep breaking the carbon bonds
Collect H’s and electrons as you go!
NAD+ becomes NADH
Electron Transport Chain
NADH drops of electrons & ATP gets made!

7. CELL RESPIRATION : pink packet p21
How exactly does your food get turned into energy?
6O2 + C6H12O6  6CO2 + 6H2O + Energy ?
Glucose
Electron transport
Glycolysis
Krebs cycle
Fermentation (without oxygen)
Alcohol or lactic acid

8. What organelle is pictured
What organelle is pictured? Why is it important to know that there are 3 steps and that they are organized like this?
Mitochondria – structure & function. By compartmentalizing parts of the process, the process is more efficient because there is a designated organelle. It’s crucial that there are two membranes – an inner & an outer because a gradient must be formed. That is the major understanding when studying this process in detail – it is a theme throughout all of biology: life will perform complicated steps and expend energy in order to set-up a reaction later.

9. Autotroph or Heterotroph?

10. Photosynthesis vs cell respiration
Look at your card & sort yourself!
Should you be in the “photosynthesis” area?
Should you be in the “cell respiration” area?
Should you stand in the MIDDLE because you do BOTH!?
