|
Definition
1)outer mitochondrial membrane
2)inner mitochondrial membrane
3)intermembrane-membrane space
4)matrix
5)cristae
6)matrix granules |
|
|
Term
| What is located on the inner mitochondrial membrane? |
|
Definition
1) cytochromes
2) dehydrogenases
3) flavoproteins |
|
|
Term
| What are the two morphologies of mitochondria? |
|
Definition
1) condensed configuration
2) orthodox configuration |
|
|
Term
| What does the condensed configuration of mitochondria refer to? |
|
Definition
| high levels of oxidative phosphorylation |
|
|
Term
| What does the orthodox configuration of mitochondria refer to? |
|
Definition
| low levels of oxidative phosphorylation |
|
|
Term
| What type of cells have mitochondria with tubular cristae? |
|
Definition
|
|
Term
| What type of cells have mitochondria with triangular cristae? |
|
Definition
| astrocytes(glial cells found in the brain and spinal cord) |
|
|
Term
| Where will you typically find mitochondria in the cell? |
|
Definition
| Near sites of high ATP utilization |
|
|
Term
| What is termed unilocular adipose tissue because each cell contains a single large droplet of fat, which displaces other organelles to the cell periphery? |
|
Definition
| White adipose tissue (WAT) |
|
|
Term
| What cell contains many fat droplets, thus termed multilocular fat? |
|
Definition
| Brown adipose tissue (BAT) |
|
|
Term
| Is WAT and BAT poorly vascularized? |
|
Definition
| No way, its richly vascularized(you should be able to see many small blood vessels when looking at a slide) |
|
|
Term
| When a thymus involutes with age, what grows to replace the tissue? |
|
Definition
|
|
Term
| At body temparture, fat droplets are... |
|
Definition
|
|
Term
| If looking at a SEM, what (collagen type) can be seen emeshing WAT cells? |
|
Definition
| reticular fibers (Collagen III) |
|
|
Term
| What protein can only be found in brown adipose tissue and with proper staining is why the tissue type is borwn? |
|
Definition
| Uncoupling protein (UCP-1- it dissipates the proton gradient before it can be used to provide the energy for oxidative phosphorylation, resulting in the production of heat instead of ATP |
|
|
Term
| Which fat type is more vascularized? |
|
Definition
| BAT- for distrubtion of the heat |
