1: The first cell was created *

A) 5 billion years ago when a lipid membrane was permeable to water

B) 4 billion years ago when a lipid membrane was permeable to water

C) 5 billion years ago when a lipid membrane was impermeable to water

D) 4 billion years ago when a lipid membrane was impermeable to water

2. If a lipid bilayer (membrane of cells) is impermeable to water, then is a lipid *

Hiint: Define the word permeable.

A) nonpolar which will not interact with the water making the membrane impermeable

B) nonpolar which will interact with the water making the membrane impermeable

C) polar which will interact with the water making the membrane impermeable

D) polar which will not interact with the water making the membrane impermeable

3. Archea and Bacteria *

A) are prokaryotes that can communicate with each other and have specialized compartments

B) are eukaryotes that can aggregate together and have specialized compartments.

C) are prokaryotes that can communicate with each other and do not have specialized compartments

D) are eukaryotes that can function in communities with each other and do not have specialized compartments

E) None of the choices are correct

4. Which of the following is not a peice of evidence supporting the idea that mitochondria in eukarotes were derived from bacteria? *

A) Mitochondria and bacteria both have their own genonme

B) Mitochondria and bacteria have 2 membranes

C): Mitochondria and bacteria have anaerobic ways to produce energy

D): Mitochondria is small like most prokaryotes when compared to eukaryote cells

E) the mitochondrial DNA is circular like plasmids in bacteria.

5. The mitochondian's genome is 3000 fold smaller than our smallest chromosome yet it *

A) contains genes for tRNA

B) contains genes for rRNA

C) contains genes for 13 proteins that help with energy production

D) is maternally inherited.

E) all of the above is true

6. There are more nuclear chromosomes in our body then Mitochondrion DNA. *

True or False

True

False

7. Which of the following is a reason why mitochondria is so efficient in producing ATP? *

A) It produces all of the proteins or complexes necessary in Cellular Respiration

B) the mitochondrial plasmid have been naturally selected for a lower number of base pairs that code for only energy producing protiens.

C) is not connected to the inner membrane that drives ATP

D) It runs completely independently of the other parts of the cell.

E) None of the choices are correct.

8. The energy produced in the Mitochondria is due to proton motor force moving small cellular machines *

True or False

True

False

9. Which represents a disorder that does not a result of a mutated mitochondria? *

A) Liver Failure

B) Deafness

C) Stroke

D) cardiomyopathy (heart disease)

E) there is no choice that is correct

10. Why are mitochondria considered semi - autonomous?

A) They resulted from endosymbiosis.

B) They have their own genome

C) they create their own proton motor force

D) They are essential for health

E) They cannot survive outside of a cell and they cannot be made by the cell

F) All of the above

Clear selection

11. Mitochondria have lost 1000's of genes from their bacterium ancestor but have developed new innovations. They include:

Check all that applies!! The class fav!

import protein from the cell made and sort them for their function.

Self-templating and growing

connect as a network with other mitochondria distributing their genome

Fuses with other mitochondia to become an efficient energy conductor

Are adaptable to the needs of all types of cell because of their dynamic behavior.

Having the abiility to communicate with other cell structures

There is nothing else because the video is over.
