12 Cards in this Set
- Front
- Back
|
Cytoplasm
|
-environment inside of the cell
-fluid environment inside boundary -may be different depending on cell type |
|
|
Nucleus
|
-double membrane
-location of DNA |
|
|
Nucleolus
|
-located inside of nucleus
-makes components of ribosomes |
|
|
Ribosomes
|
-not bound by a membrane
-made of protein and RNA -organized into components -small and large sub units - large(30s or 40s) - small(50s-60s) |
|
|
Rough Endoplasmic Reticulum(RER)
|
-ER developed as an offshoot of the membrane of the nucleus
-ribosomes attached -makes secretory proteins |
|
|
Smooth Endoplasmic Reticulum(SER)
|
-makes membranes(phospholipids)
-carbohydrate metabolism -storage(ions especially Ca2+) |
|
|
Golgi Complex
|
-membrane stacks
-recieves secretory proteins from RER -modifies proteins -sometimes proteins are inactive, golgi will make it active -transports protein to correct destination -has a CIS and Trans side |
|
|
Mitochondria
|
-usually many in a cell
-round outer membrane, convoluted inner membrane -makes ATP (energy) adenosine triphosphate -part of cellular respiration |
|
|
Chloroplasts
|
-many in a cell
-double membrane -makes energy in a form of sugars |
|
|
Lysosomes
|
-single membrane
-contains enzymes and altered pH(acidic) - breaks down (degrades biological molecules. |
|
|
Peroxisome
|
-single membrane
-breaks down molecules through oxidation -O2-->O- O- is highly reactive -creates H2O2 |
|
|
Vacuoles
|
-large size, single membrane
-food vacuole=stores starch or other energy compounds -central vacuole=stores various things, like food, pigments, ions, waste -contractile vacuole=regulates H2O |
