1.            
Cell Energy

2. Law Conservation of Energy
Antoine Lavoisier, 1778, Father of Modern Chemistry
Law Conservation of Energy

3. It is transferred by ATP: Adenosine tri-phosphate
Law of Conservation:
The amount of energy always the same.
It is neither used up or made.
It is never created or destroyed.
What is Energy?
The ability to do work
It is transferred by ATP:
Adenosine tri-phosphate

4. YOYO (Your on your own) Draw a picture of
Anabolism
Catabolism
SB: (shoulder buddies) Compare and correct each others drawings

5. Catabolic Reactions Anabolic Reactions
SB: Give 2 examples of catabolism &
2 examples of anabolism.

7. ATP goes through a cycle when carrying ENERGY
3 Phosphate groups to
2 Phosphate groups
Adenosine TRIphosphate
turns into
Adenosine DIphosphate
ATP
ADP
Energy Out
Energy In

8. ENERGY IS STORED ON THE BONDS BETWEEN THE PHOSPHATES

9. Oxygen is required for ATP to work.
HOW??
Hydrolysis
Energy Released Energy Stored
TB:(triangle buddies) Describe how energy is released and stored in the cell.
Oxygen is required for ATP to work.

11. Energy Connections Plankton, Algae Sunlight has energy.
Plants take in the energy
Autotrophs –
Make their own food
Called Producers
Make food through
Photosynthesis:
Plankton, Algae
Corn, Fruit Trees
SB: Why are plankton and Algae in bold?

12. Chloroplast collect the sun’s energy through photosynthesis
Chloroplast collect the sun’s energy through photosynthesis. The mitochondria use it in cellular respiration.

13. Heterotrophs are consumers.
Sun light energy is transformed
Into chemical energy in plants.
We get the sun’s energy by
eating plants and animals that eat plants.

14. There is a 10% loss of original energy as it climbs higher in the energy pyramid

15. TB: Explain to 2 others: How much energy is passed on in the energy pyramid

16. Anaerobic Reactions Do not use Oxygen Creates a little of energy
Aerobic Reactions Require Oxygen Creates LOTS of energy 32 ATP is made from 1 glucose 32
ATP
Anaerobic Reactions Do not use Oxygen
Creates a little of energy
2 ATP is made from 1 glucose 2
ATP

17. The powerhouse of the cell
Cellular Respiration
takes place in all cells
in the
Mighty Mighty
Mitochondria
The powerhouse of the cell

18. Where in the cell does ATP become ADP?

19. SB: Review QUESTIONS:
How is ATP formed?
Where is the energy stored in an ATP molecule
How does ATP give energy to the cell?
What is left after an ATP
molecules loses a phosphate group?
5. What part of the cell processes enegry?

20. Enzymes, made of protein break down carbohydrates.
Lactase breaks down Lactose
Maltase breaks down Maltose
Sucrase breaks down Sucrose
Enzymes, made of protein
break down carbohydrates.

21. Cellular Respiration
Is the process that releases energy by breaking down food molecules in the presence of oxygen.
Occurs in the mitochondria of the cell.

22. Hypoglycemia: There’s not enough ingredients for cellular respiration:
H, C, O  H2O, CO2, C6H12O6 (glucose)
Mitochondria can’t make ATP (energy)
Hypoglycemia causes
Dizziness
Weakness
Nausea
Trembling polysaccharide
Confusion
May seem ‘drunk’

23. PLEASE return to the Biology FOLDER
5/19/2018
Hyperglycemia
Too much sugar: ATP energy in blood
Diabetes
Hyperactive kids on sugar

24. How is photosynthesis similar and different from cellular respiration?
Where is Anabolism and Catabolism? How do fossils fit in?
What is the path of solar energy? Is the energy used up?

25. How is cellular respiration by plants similar to the burning of fossil fuels?

26. A. Both release CO2 compounds. (containing carbon)
How is cellular respiration by plants similar to the burning of fossil fuels?
A. Both release CO2
Global Warming increases
Animals breath out CO2 B. Break down organic
compounds.
(containing carbon)

27. C. Both produce ATP.
(energy in the mitochondria) D. Both absorb light.

28. Are fossil fuels produced by photosynthesis?

29. How are fossil fuels produced by photosynthesis?
Plankton capture CO2.
Plankton use photosynthesis to break the chemical bonds between Carbon//Oxygen.
Energy is released & used by plankton to move, reproduce, move towards light . . .
They die and sink to the ocean bottom.
They are ‘cooked’ by the heat/pressure of the earth. (The core of the earth is molten lava!)
They make coal, shale, oil or natural gas, depending on the depth at which they sink.
