Term
| what is the structure, function and location of the golgi? |
|
Definition
str: series of stacked membranes
func: site of sorting, packaging and shipping of proteins for ER export
-make compound molecules
location: usually v. close to the ER |
|
|
Term
| how does a cell send a protein out of the cell? |
|
Definition
1. makes protein in rough ER
2. vesicle moves protein to face of Golgi
3. protein passes through Golgi, modified as needed
4. Golgi takes all the proteins leaving cell and packages them into a vesicle
5. vesicle fuses with cell membrane; protein expelled. |

Term
| where does the Golgi send proteins that are NOT leaving the cell? |

|
Term
| peroxisome func, location, structure |
|
Definition
func: vesicle with specialized enzymes to breakdown dangerous free radicals. i.e. converts O (w/one lone e-) to H2O2
location: in the cytoplasm
structure: vesicle |
|
|
Term
| Mitochondrion: stur, func, loc |
|
Definition
structure: organelle with outer membrane, inner membrane, space between is the "inter membrane space", inside the inner membrane is the matrix, and the folds are crista(e)
function: location where lots of ATP are made
location: organelle in the cytoplasm
**double membrane feature is very important |
|
|
Term
| Eptheilial Cells: str, func, loc |
|
Definition
struc: one side that faces in cell is flat the other side has microvilli facing the food stream--lots of surface area, so good for catching food
func: to create a barrier between a void and an underlying tissue
location: between void and tissue |
|
|
Term
| what is a "polarized" cell? |
|
Definition
| a cell that has a different function on either side of the cell (i.e. microvilli vs. flat) |
