Connecting Photosynthesis & Cell Respiration
• Are you ready to turn in homework tomorrow?
which did you do?• How to study for the
quiz?– Pink packet pages 20-25– Review your homework– Look at the powerpoint
online
• Time for a Brain Check!!

LIGHT-DEPENDENT Reaction occurs in thylakoid membrane
Carbon Cycle Reaction occurs in stroma
Photosynthesis vs Cell Respiration
What similarities do you see?
Chemical Energy and Food
The two equations are exact opposites!
PHOTOSYNTHESIS
___________ + _________ + ___________ →_______________ + __________6 CO2 6 H2O C6H12O6 6O2
_____________ + _________ →________ + __________ + __________
CELLULAR RESPIRATIONC6H12O6 6O2
6 CO2 6 H2O
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
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!

What organelle is pictured?
Why is it important to know that there are 3 steps and that they are organized like this?
Autotroph or Heterotroph?
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!?
