No, ribosomes are not always attached to the rough endoplasmic reticulum (RER). While ribosomes are primarily found on the surface of the RER, where they synthesize proteins destined for secretion or membrane insertion, free ribosomes also exist in the cytoplasm. These free ribosomes synthesize proteins that function within the cytosol. The attachment of ribosomes to the RER is a dynamic process that occurs based on the specific needs of the cell.
What else can I help you with?
What is ER with ribosomes attached to its surfaces?
ER with ribosomes attached to its surfaces is called rough endoplasmic reticulum (RER). RER is involved in protein synthesis as the ribosomes attached to it synthesize proteins that are then transported and modified within the ER. The RER is characterized by its bumpy appearance due to the presence of ribosomes.
Are ribosomes found on the RER?
yes they are attached with RER and therefore give the rough appearance to them as compared wtih SER
What internal transport system without ribosomes attached?
This called the rough endoplasmic reticulum or RER.
What are membranes folds inside the cell that have ribosomes stuck to them?
Membrane folds inside the cell with ribosomes attached are called rough endoplasmic reticulum (RER). They are involved in protein synthesis and processing. The ribosomes on the RER give it a "rough" appearance under a microscope.
Are ribosomes floating freely in the cytoplasm?
Yes. Ribosomes are found both freely floating and attached to the endoplasmic reticulum.

What is the ER with ribosomes attached to its surface?
The endoplasmic reticulum (ER) with ribosomes attached to its surface is called rough endoplasmic reticulum (RER). Ribosomes on the RER are responsible for protein synthesis, which is then transported throughout the cell or secreted outside the cell.
Why does rough ER look rough under the microscope?
ribosomes attached on the sides of the RER makes it look rough under the microscope .
What internal transport system without ribosomes attached?
This called the rough endoplasmic reticulum or RER.

Yes. Ribosomes are found both freely floating and attached to the endoplasmic reticulum.
What is the constructive site of a protein?
The Endoplasmic Reticulum-ally attached Ribosomes; also known as the rough endoplasmic reticulum or RER.
What is a construction site of a protein?
The Endoplasmic Reticulum-ally attached Ribosomes; also known as the rough endoplasmic reticulum or RER.
Functional difference between RER and SER?
rough endoplasmic reticulum[RER] has ribosomes attached to it giving a rough appearance thereby deriving its name. smooth endoplasmic reticulum[SER] is devoid of ribosomes. RER- involved in protein synthesis as ribosomes are concerned with protein synthesis. SER-concerned with lipid synthesis in intestinal cells& with steroid formation in adrenals
How is rough endoplasmic recticulum different from smooth endoplasmic recticulum?
rough endoplasmic reticulum (RER) has ribosomes attached to it but SER doesn't
Does the smooth er transport proteins?
The smooth endoplasmic reticulum (SER) does not have ribosomes attached to it and only makes lipids. The rough endoplasmic reticulum (RER), on the other hand, does have ribosomes attached to it. The RER makes lipids as well but also helps transport the proteins made by the ribosomes attached to it.
