2. Let’s get Physical! What are they doing in the video?
Why are they breathing so hard?

3. Why do cells need energy?

4. All organisms need energy for:
Active transport
Cell division
Movement
Production of proteins
Where do we get the energy we need to live?
From the food we eat!
Food gets broken down so small that it makes its way to all your cells.

5. Mitochondria are referred to as “the powerhouses” of the cell.
Simply stated, the mitochondria make chemical energy in the form of ATP to power the cell.

6. This energy is stored and released using a molecule called ATP
Once the food is inside your cells, the mitochondria take charge and crack the chemical bonds in the food you eat.
This energy is stored and released using a molecule called ATP

7. ADP ATP ATP: energy molecule- basic energy source for all cells
living things use ATP to store and release energy
like a tiny, fully charged battery
ADP
made when energy is released from ATP
like a tiny, partially charged battery
ADP
ATP

8. What about oxygen?
What do food and mitochondria have to do with breathing and oxygen and respiration?

9. “in the presence of oxygen”
Aerobic means
“in the presence of oxygen”

10. Cellular respiration…. (aerobic)
is the process by which cells take in food (glucose), and oxygen
and release carbon dioxide, water, and energy (ATP)

11. Cellular (aerobic) respiration in the mitochondria

12. Cellular (aerobic) respiration has 3 main parts:
Glycolysis
One molecule of glucose is broken into 2 molecules of pyruvate, a 3-carbon compound
Takes place in the cytoplasm
Draw a simple diagram of a mitochondrion
on the left side of your NB

13. 2. Krebs Cycle
Takes place in the mitochondria
Pyruvate is broken down into carbon dioxide

14. 3. Electron Transport Chain (ETC)
oxygen goes in
takes place in the mitochondria
turns ADP into ATP (it charges the batteries!) and produces water

16. Cellular (aerobic) Respiration Equation:
((reactants))  ((products))
C6H12O O  6 CO H2O + energy
Glucose + oxygen  carbon dioxide + water + energy

17. Both plants and animals
need to break down food to get energy
have mitochondria
perform cellular (aerobic) respiration

18. Quickcheck: What are the three parts of Cellular Respiration?
Where do they each take place?

19. Mitochondria have their own DNA and ribosomes!
