What ER does not have ribosomes attached? · The smooth endoplasmic reticulum (ER) does not have ribosomes attached to its surface. It is involved in lipid metabolism, detoxification, and calcium storage. What part of the cell is responsible for making proteins? · There is no specific part of the cell, other than in the ribosome. The ribosome is the part that makes the protein at the end of the process known as protein synthesis. Ribosomes are actually proteins themselves, and are called rRNA...
More answers ; The rough endoplasmic reticulum (RER) is connected to the nuclear envelope, which is a double membrane surrounding the nucleus of a eukaryotic cell. Ribosomes attached to the RER play a crucial role in protein synthesis and modification. nuclear membrane. To the nuclear membrane. smooth er. y’all r dumb

Smooth endoplasmic reticulum (ER) is formed through the extension and branching of membrane tubules that lack ribosomes, in contrast to rough ER which has ribosomes attached to its surface. The smo...
Dictionary > Ribosome · Ribosome ; Figure 3: The “central dogma” of life governs the conversion of genetic code from DNA to RNA to proteins. The process of conversion of DNA to RNA is called transcription and the process of conversion of RNA to proteins with the help of ribosomes in a cell is called translation.

The SER lacks ribosomes embeded within the membrane of the ER. The "rough" description is given due to the visible ribosomal bodies covering the exterior surface.
