Rough Indoplasmic Reticulum
|
|
Definition
| takes proteins made in surface ribosomes inside its internal spaces and adds carbs & lipid groups to them, making glycoproteins and lipoproteins. Location of the molecular chaperones. Main site for making new membranes |

|
|
Definition
| has many membranes in internal spaces, modifies proteins, breaks down & produces lipids and glycoge, detoxifies poisons |
|
|
Term
|
Definition
| modifies molecules from endoplasmic recticulum (esp. by modifying carb groups on proteins and lipids), makes polysaccharides, and packages material in vesticles for secretion |
