Within the endoplasmic reticulum (ER), proteins undergo crucial processes such as folding, post-translational modifications, and quality control. The rough ER, studded with ribosomes, synthesizes proteins destined for secretion or for use in the cell membrane. Once synthesized, these proteins are folded into their functional shapes and may receive modifications like glycosylation. Misfolded proteins are identified and targeted for degradation to ensure cellular health.
What else can I help you with?
What transports newly made proteins?
The endoplasmic reticulum transports newly made proteins within the cell. Proteins are synthesized on ribosomes attached to the rough endoplasmic reticulum, and then they are folded and transported to their final destination within or outside the cell.
What is endoplasmic reticulum and ribosomes?
The endoplasmic reticulum is a network of membranes within cells that is involved in protein and lipid synthesis. Ribosomes are cellular structures where proteins are synthesized, either free-floating in the cytoplasm or attached to the endoplasmic reticulum. Together, they play a crucial role in the production and transportation of proteins within the cell.
Endoplasmic reticulum where proteins are built?
The endoplasmic reticulum is an organelle in the cell where proteins are synthesized, folded, and modified. It plays a crucial role in protein production and quality control before they are transported to their final destinations within or outside the cell. There are two types of endoplasmic reticulum: rough endoplasmic reticulum (with ribosomes attached) and smooth endoplasmic reticulum (without ribosomes).
What is covered by ribosomes and sends it modified protein to the Golgi aperatus?
The ribosome covered organelle that modifies and sends out proteins is the rough endoplasmic reticulum. The ribosome is a cellular structure on which proteins are made. The rough endoplasmic reticulum synthesizes and packages proteins.
Organelles that produce proteins used within the cell are?
Ribosomes and the endoplasmic reticulum are two organelles involved in protein production within the cell. Ribosomes are responsible for protein synthesis, while the endoplasmic reticulum aids in the processing and modification of these proteins before they are transported to their final destinations.
What transports newly made proteins?
The endoplasmic reticulum transports newly made proteins within the cell. Proteins are synthesized on ribosomes attached to the rough endoplasmic reticulum, and then they are folded and transported to their final destination within or outside the cell.

The endoplasmic reticulum is a network of membranes within cells that is involved in protein and lipid synthesis. Ribosomes are cellular structures where proteins are synthesized, either free-floating in the cytoplasm or attached to the endoplasmic reticulum. Together, they play a crucial role in the production and transportation of proteins within the cell.
In which organelles are proteins made?
Proteins are made in ribosomes, which can be free-floating in the cytoplasm or attached to the endoplasmic reticulum. Once synthesized, proteins may undergo processing and modification in the endoplasmic reticulum and Golgi apparatus before being transported to their final destination within the cell.
What is an extensive system of internal membranes that move proteins and other other substances through the cell?
endoplasmic reticulum
Where are proteins modified after they are made?
Proteins are modified after they are made in the endoplasmic reticulum and Golgi apparatus within the cell.
What happens to secretory proteins when they are transported out of the rough endoplasmic reticulum?
When secretory proteins are transported out of the rough endoplasmic reticulum, they are packaged into vesicles and sent to the Golgi apparatus for further processing and sorting. In the Golgi apparatus, the proteins undergo modifications and are sorted into different vesicles for transport to their final destination within or outside the cell.
Function of the rough endoplasmic reticulum?
The rough endoplasmic reticulum is involved in protein synthesis and modification. It has ribosomes attached to its surface that facilitate the synthesis of proteins that are then processed and packaged for transportation within the cell or secretion outside of the cell.
Endoplasmic reticulum where proteins are built?
The endoplasmic reticulum is an organelle in the cell where proteins are synthesized, folded, and modified. It plays a crucial role in protein production and quality control before they are transported to their final destinations within or outside the cell. There are two types of endoplasmic reticulum: rough endoplasmic reticulum (with ribosomes attached) and smooth endoplasmic reticulum (without ribosomes).
Endoplasmic reticulum is best described as a?
The endoplasmic reticulum is best described as a network of membranes within cells that is involved in the synthesis, folding, and transport of proteins and lipids. It can be classified into rough endoplasmic reticulum (with ribosomes on its surface) and smooth endoplasmic reticulum (lacking ribosomes).
What is covered by ribosomes and sends it modified protein to the Golgi aperatus?
The ribosome covered organelle that modifies and sends out proteins is the rough endoplasmic reticulum. The ribosome is a cellular structure on which proteins are made. The rough endoplasmic reticulum synthesizes and packages proteins.
The rough endoplasmic reticulum provides a mechanism for the transfer of what?
The rough endoplasmic reticulum provides a mechanism for the transfer of proteins within the cell. It serves as a site for protein synthesis and modification before the proteins are sent to their final destination in the cell.
Which cell organelle where proteins are made?
Ribosomes within the cytosol (if they are free) or within the endoplasmic reticulum (if they are membrane bound) are responsible for making proteins.
