5. SUNLIGHT IS THE MAIN SOURCE OF ENERGY FOR LIFE ON EARTH

6. ALL ENERGY comes from the ____ .
sun

7. There are 3 types of energy:
Heat
_______
Chemical
light

8. Food stores _________ energy
chemical

9. energy Food is not an usable form of ___________ energy in cells
It must be converted to a usable form

10. ATP Food is changed into Adenosine TriPhosphate
(ATP): chemical fuel that powers cell’s activities

11. ATP: Adenosine Triphosphate

12. ATP
ATP  ADP
Terminal phosphate bond is broken
Energy is released

13. ATP
ADP = Adenosine DiphosPhate
2 phosphates instead of 3

14. ATP
ADP  ATP
Phosphate added ADP

15. ATP Energy released from ATP is used to… Power active transport
Power the sodium- potassium pump
Power movement of organelles within the cell
ATP

16. ATP
Cells store small amounts of ATP because it is inefficient for storing energy

17. Energy from carbohydrates used to make ATP from ADP as needed

18. When you exercise, ATP stored in muscles is used first.
Cellular respiration
When you exercise, ATP stored in muscles is used first.

19. Cellular respiration
Lactic acid fermentation
Muscles low on O 2 begin producing ATP through _______ ___ _____________ .

20. Lactic acid is eliminated by heavy breathing (taking in more O 2 ).
Cellular respiration
Lactic acid is eliminated by heavy breathing (taking in more O 2 ).

21. Electron Transport Chain
Cellular respiration
Glucose (C6H1206) +
Oxygen (02)
Glycolysis
Krebs Cycle
Electron Transport Chain
Carbon
Dioxide
(CO2) +
Water
(H2O)
Cellular respiration can produce ATP for exercise lasting about 30 minutes.

22. What is cellular respiration’s primary goal?
To make energy. But it also produces carbon dioxide & water.

23. C6H12O6 + 6O2  6CO2 + 6H2O + Energy

24. photosynthesis
Plants are autotrophs that use photosynthesis to make their own ______ .
food

25. as reactants for photosynthesis.
Plants need ____ & ____
as reactants for photosynthesis.
Water & carbon dioxide

26. These reactants come from ___ ______ .
photosynthesis
These reactants come from ___ ______ .
Cellular respiration

27. What is photosynthesis’ primary goal?
To make glucose (food) for plants. But it also produces oxygen!

28. carbon dioxide + water  glucose + oxygen
light
6CO H2O  C6H12O O2
carbon dioxide + water  glucose + oxygen
