What are the types of proteins that are synthesized in the rough ER?
Proteins synthesized in the rough endoplasmic reticulum (rough ER) primarily include secretory proteins, membrane proteins, and lysosomal proteins. These proteins are typically synthesized with an N-terminal signal peptide that directs them to the rough ER, where they undergo co-translational translocation into the lumen. Additionally, the rough ER is involved in the initial stages of post-translational modifications, such as glycosylation, which are essential for the proper functioning of these proteins.
What type of proteins are made in the ER?
Proteins synthesized in the endoplasmic reticulum (ER) include secretory proteins, membrane proteins, and proteins destined for lysosomes. The rough ER, which is studded with ribosomes, is primarily responsible for producing these proteins, which undergo folding and modifications like glycosylation. Once synthesized, they are packaged into vesicles for transport to their final destinations, such as the Golgi apparatus.
What is a flattened membrane that packages proteins?
The endoplasmic reticulum (ER) is a flattened membrane that packages proteins. It plays a critical role in the synthesis, folding, and sorting of proteins. The ER consists of two main regions: the rough ER, which is studded with ribosomes and involved in protein synthesis, and the smooth ER, which lacks ribosomes and is involved in lipid metabolism and detoxification.
Which cell part is maze of folded membranes where proteins and lipids are produced?
The endoplasmic reticulum (ER) is the cell part that is a maze of folded membranes where proteins and lipids are produced. There are two types of ER: rough ER, which has ribosomes attached to its surface and is involved in protein synthesis, and smooth ER, which is involved in lipid synthesis.
In plant cells where are proteins synthesized?
Proteins are synthesized in plant cells at ribosomes, which can be found in the cytoplasm and on the endoplasmic reticulum (ER). The ribosomes on the ER are involved in synthesizing proteins that will be transported and modified within the ER and Golgi apparatus before reaching their final destination within the cell.
What are found on the ER and manufacture proteins?
Ribosomes are the structures found on the ER that manufacture proteins.
What happens to proteins that lack er signal sequence?
Proteins that lack an ER signal sequence are released into the cytosol.
What is Endoplasmic role?
First phases of glycosylation of proteins proceeds there, lipids are synthetized there and mainly, intermembrane proteins and proteins to be excreted out from the cell are synthetized into inside of ER (ribosomes synthetizing these proteins land on the ER surface and synthetize new protein directly into ER).
What are the types of proteins that are synthesized in the rough ER?

Proteins are made in cells on the?
ER
Which molecules are processed by the rough endoplasmic reticulum (ER)?
Proteins are the main molecules processed by the rough endoplasmic reticulum (ER). The ribosomes on the rough ER synthesize proteins, which are then folded and modified as they pass through the ER. Additionally, some lipids are also synthesized and processed in the ER.
What type of proteins are made in the ER?
Proteins synthesized in the endoplasmic reticulum (ER) include secretory proteins, membrane proteins, and proteins destined for lysosomes. The rough ER, which is studded with ribosomes, is primarily responsible for producing these proteins, which undergo folding and modifications like glycosylation. Once synthesized, they are packaged into vesicles for transport to their final destinations, such as the Golgi apparatus.
What is rough ER?
rough ER, helps produce proteins and is covered in ribosomes.
Are chromosomal proteins made in cytoplasm?
Proteins are made in the ER and golgi, not the cytoplasm.
Which statement most accurately describes what happens to proteins that lack an ER signal sequence?
Proteins lacking an ER signal sequence will not be translocated into the endoplasmic reticulum (ER) for proper folding. Instead, they will remain in the cytoplasm, where they may either function as cytoplasmic proteins or be targeted for degradation by the proteasome if they are misfolded or damaged.
What is a flattened membrane that packages proteins?
The endoplasmic reticulum (ER) is a flattened membrane that packages proteins. It plays a critical role in the synthesis, folding, and sorting of proteins. The ER consists of two main regions: the rough ER, which is studded with ribosomes and involved in protein synthesis, and the smooth ER, which lacks ribosomes and is involved in lipid metabolism and detoxification.
What does each type of ER produce?
Smooth ER synthesizes lipid, while the rough ER makes proteins for the cell.
