Endoplasmic reticulm Flashcards
Endoplasmic reticulm
Constitutes roughly have of all plasma membrane in a cell . two types of endoplasmic reticulm
Rough ER
has ribosomes on the surface
Continuous with nuclear envelope
Synthesize poly peptide
Connected to the outer nuclear membrane, forming flatten sacs
Smooth ER
Does not have ribosomes on the surface
More tubular in shape than rough ER
Lack ribosomes
Synthesize of lipids, such as phospholipid, lipids, and cholesterol
Store is calcium ions and regulates muscles
What type of network does ER have?
network that compromises transport system of cell
Fused with
nuclear membrane and extends through cytoplasm of the cell membrane
Rough Endo plasmic reticulum site of ribosomes
Proteins that are associated with plasma membrane, or synthesize on ribosomes that bind to the cytoplasmic side of rough endoplasmic reticulum
Rough and smooth endoplasmic reticulum
Both consist of series of continuous membrane called cisternae
Rough and smooth endoplasmic reticulum
Both consist of series of continuous membrane called cisternae
What remains in the side of saw of the cell of rough ER?
Proteins that are produced remain in the side of saw cell
