1. PHOTOSYNTHESIS…. Using sunlight to make sugar …….AND CELLULAR RESPIRATION Using sugar to make energy Moo.

2. The Players IN PLANTS ONLY Chloroplasts - Organelles found only in plant cells that carry out photosynthesis. Mitochondria - Organelles found in plant and animal cells that carry out cellular respiration. (Cows have no chlorplasts. If they did, they ’ d be green.)..and what’s in them. IN BOTH

3. Photosynthesis Sun Energy Water H 2 O Carbon Dioxide CO 2 Glucose C 6 H 12 O 6 Oxygen O 2 Chloroplast

4. Cell Respiration C 6 H 12 O 6 Glucose Oxygen O 2 CO 2 Carbon Dioxide H 2 O Water Energy (Stored in ATP)

5. RESPIRATION CARBON DIOXIDE ENERGY C 6 H 12 O 6 + GLUCOSE 6O 2 OXYGEN produces 6CO 2 + 6H 2 O + WATERATP PHOTOSYNTHESIS produces 6CO 2 + CARBON DIOXIDE 6H 2 O + WATER SUN + ENERGY C 6 H 12 O 6 + GLUCOSE 6O 2 OXYGEN

6. MORAL OF THE STORY: One organelle’s trash is another organelle’s treasure.

7. But what if there isn’t much oxygen available? Can cellular respiration still occur?

8. Yes. Fermentation Yeast Cells (Anaerobic Respiration) BEER! Less ATP Ethanol Animal Cells Less ATP Lactic Acid CRAMPS! Products
