Mammalian cell Flashcards
Cell membrane
A thin envelop that regulates the entry and exit of various molecules
Double membrane made of phosolipids
Encloses the liquid phase of the cell
Four fundamental parts
Cell membrane
Cytoplasm
Organelles
The inclusion
Cytoplasm
Liquid phase of cell
Contains the organelles
Nucleus
Found at the center (not always)
Contains chromatin in its center
Chromatin
Loosely coiled DNA
Nucleoplasm
Liquid phase of the nucelus
Suspends the chromatin
Nuclear membrane
Limiting envelope surrounding the nucelus
Contains pores allowing for molecules to pass btw the cytoplasm and nucleoplasm
Nucleoli
In the nucleus
One to four inside
Concerned with protein synthesis
Ribosomes
Produced by rough endoplasmic reticulum as projections on its outside surface
Rough endoplasmic reticulum
Protein synthesis
Smooth endoplasmic reticulum
Lipid and steroid synthesis
Golgi appartus
Package protein released from the rough endoplasmic reticulum
Cytoplasmic secretory vesicles
Packaged protein ready for cellular use or export
Mitochondria
Double layered sphe
Polyribosomes
Groups of ribosomes that have similar structure abd function to ribsomes from Rough ER but freely float
