What can the rough endoplasmic reticulum be compared to?
The endoplasmic reticulum is like the highway system because the cell uses the endoplasmic reticulum to move material throughout the cell like people use highways to move throughout the country.
What everyday object is like rough ER?
Analogy: The rough ER is like an assembly line because ribosomes are positioned on rough endoplasmic reticulum where the proteins are assembled. Workers gather in regions of the factory where the assembly takes place.
What type of proteins are made in the rough ER?
3.4 Ribosome-binding proteins Rough ER contains two integral membrane proteins, ribophorins I and II, that have molecular masses of 65 kDa and 63 kDa, respectively. These proteins remain attached to ribosomes when the ER membrane is dissolved with detergent and they can be crosslinked to ribosomes by chemical reagents.
What is the function of the rough endoplasmic reticlum?
Rough Endoplasmic Reticulum Function: The majority of the functions of rough ER is associated with protein synthesis. Rough endoplasmic reticulum also plays a vital role in protein folding. Also ensures quality control (regarding correct protein folding). The second most important function after protein synthesis and protein folding is protein sorting.
What does process take place in the rough endoplasmic reticulum?
Ribosomes on the rough endoplasmic reticulum are called ‘membrane bound’ and are responsible for the assembly of many proteins. This process is called translation .
What does rough endoplasmic reticulum have attached to it?
Rough endoplasmic reticulum has ribosomes attached with them on their surface which give them granular appearance while smooth endoplasmic reticulum do not have ribosomes attached with them and thus they have smooth, tube-like and uniform appearance.
What makes the ER rough?
Rough ER is so named as it has a rough or granular appearance. This is due to the fact that there are a number of ribosomes attached to the membrane. Ribosomes are tiny organelles that are made of RNA and protein. They can be found free-floating in the cytoplasm of the cell and also attached to the ER.
