|
Term
|
Definition

-nuclear membrane=selectively permeable
|
|
|
Term
| Function of the Plasma Membrane |
|
Definition
-physical barrier
-promotes specific chamical reactions
-selectively permeable
-communicates with other cells
-responds to external stimuli |
|
|
Term
| Function of the Cytoplasm |
|
Definition
-made of the cytosol; water & proteins
-houses cell structures, including the cytoskeleton
|
|
|
Term
|
Definition
| -house genetic material, composed of chromosomes |
|
|
Term
| Differnce b/w the DNA in a prokaryotic cell and a eukaryotic cell |
|
Definition

|
|
Term
|
Definition
-lipid metabolism
-composed of lumen, which is separate from the cytoplasm
-continuous with the nuclear membrane |
|
|
Term
|
Definition
| Important in lipid synthesis and metabolism |
|
|
Term
|
Definition
| -synthesize proteins to be secreted from the cell (why rough? its studded w/ ribosomes) |
|
|
Term
| Function of the Golgi Apparatus |
|
Definition
| adds sugar to proteins from the Rough ER |
|
|
Term
| Function of the Cytoskeleton |
|
Definition
-provides shape, structure, and motility
-serves as a network cell structures |
|
|
Term
| The 3 types of Cytoskeleton Fibers |
|
Definition
1) Macrotubuoles: found in flagella and cilia, made of tubulin
2) Intermediate Filaments: thought to give mechanical strength to specific cells (such as neurons(neurofilaments))
3) Microtubuoles: made of actin, work with motor protein myosin to facilitate protein movement |
|
|
Term
