Rough Endoplasmic Reticulum
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
The rough endoplasmic reticulum is a membrane network studded with ribosomes that modifies newly made proteins and synthesizes membrane phospholipids.
Show
Liver cells, which secrete large amounts of protein, carry an especially dense rough endoplasmic reticulum.
Watch for
The rough ER's ribosomes sit on its cytoplasmic surface — they are the same ribosomes described at Bio 0269, only positioned differently.
