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!?
