1. Structure and Function of the Mitochondria

2. Structure of Mitochondria
Organelle with two membranes
Found in both Prokaryotic and Eukaryotic Cells
In humans all of your mitochondria come from your mother
Have their own DNA

4. Structure is a double membrane with many folds on the inner membrane

5. Function of the Mitochondria
“Powerhouse of the cell”
Convert chemical energy stored in food into forms that the cell can use
Site of cellular respiration

6. Cellular Respiration C6H12O6 + 6O2 6CO2 + 6H2O Memorize this formula
In words: The bonds in Sugar are broken apart. Energy is released and Carbon Dioxide and water are given off as waste

7. The energy released is not directly usable by the cell.
It is used to convert ADP (Adenosine Diphosphate) to ATP (Adenosine Triphosphate)

8. Energy

9. When ATP releases the phosphate energy is released that the cell can use

11. Endosymbiotic Hypothesis
Symbionts live together in a situation in which both benefit
Get this – mitochondria have their own DNA and ribosomes
They also divide just like bacteria
Sooo – it could be that mitochondria are bacteria that invaded eukaryotic cells.
Both would benefit

12. All of your mitochondrial DNA came originally from your mother.
