1. Label Cell A
Label Cell B
What are the “raw materials” of photosynthesis?
What are the 2 jobs of the guard cell?
Where do organic molecule store their energy?

3. Guard Cells Open stomata to allow gas exchange
Close stomata to regulate water loss

4. Cellular Respiration

5. Organic Molecules Organic molecules contain BOTH carbon and hydrogen
Organic molecule store energy in the bonds between their atoms
Organic molecules store chemical energy.
All organisms need organic molecules to make energy.

6. Where do Organic Molecules come from?

7. Where do Organic Molecules come from?
Producers (autotrophs) make their own organic molecules using the sun.
Consumers (heterotrophs) must get their organic molecules from other organisms

8. ALL living things release energy from organic molecules during cellular respiration.
Cellular respiration is the process by which organisms use oxygen and organic molecules to make ATP energy.
Carbon dioxide and water are released as waste products

9. Cellular respiration takes place in the mitochondria of every single cell.
enzymes

10. Cellular respiration takes place in the mitochondria of every single cell.
enzymes
Oxygen + glucose ----> Carbon dioxide + water + ATP

11. Cellular respiration takes place in the mitochondria of every single cell.
enzymes
Oxygen + glucose ----> Carbon dioxide + water + ATP
O C6H12O > CO H2O + ATP

12. ATP

13. Photosynthesis converts light energy into chemical energy (glucose).
Cellular respiration converts chemical energy into ATP energy.
ATP is the energy used to power all cell activities
