The Endoplasmic Reticulum
An attached ribosome is a ribosome that is bound to the endoplasmic reticulum (ER) membrane. It is involved in the synthesis of proteins that are either secreted by the cell or inserted into the membrane. These proteins play crucial roles in various cellular functions.
After proteins get modified in the Endoplasmic Reticulum, they are transported through the golgi apparatus where they get packaged into vesicles to late be secreted out of the cell or to be used within the cell.
through active transport, as transport proteins are needed to fit them through the phospholipid bilayer. this requires energy, as the proteins are doing a lot of work to move the large molecules.
Yes they are found as integral membrane proteins in addition to lipidis, glycerol and proteins alone. Glycoproteins are proteins that are post translationally coneected to sugar chains. Mostly the secreted proteins are also glycoslated.
The organelles involved in processing proteins include the endoplasmic reticulum (ER) and the Golgi apparatus. The rough ER is responsible for synthesizing proteins, particularly those that are secreted or membrane-bound, while the smooth ER is involved in lipid synthesis and detoxification. Once synthesized, proteins are transported to the Golgi apparatus, where they undergo further modifications, sorting, and packaging for delivery to their final destinations. Additionally, ribosomes play a crucial role in translating mRNA into polypeptide chains, initiating the protein synthesis process.
Free ribosomes synthesize proteins that are soluble in the cytoplasm, such as enzymes, structural proteins, and proteins involved in intracellular signaling pathways. These proteins do not have a specific subcellular localization and function within the cytoplasm of the cell.

The liver produces the proteins that are secreted into the blood. The liver is responsible for protein metabolism, degradation and synthesis
the endoplasmic reticulumn is the site where lipid components of the cell membrane are assembled, along with proteins and other materials that are exported from the cell.
through active transport, as transport proteins are needed to fit them through the phospholipid bilayer. this requires energy, as the proteins are doing a lot of work to move the large molecules.
New proteins are moved to the cell surface and secreted through a process called vesicle trafficking. Proteins destined for the cell surface are synthesized by ribosomes attached to the endoplasmic reticulum, folded properly in the Golgi apparatus, and then packaged into vesicles for transport to the cell membrane for secretion. These vesicles fuse with the plasma membrane, releasing the proteins outside the cell.
The endoplasmic reticulum is an organelle that transports materials within a cell. It can be classified into two, namely: the rough endoplasmic reticulum which has ribosomes and the smooth endoplasmic reticulum which does not have ribosomes.
Yes they are found as integral membrane proteins in addition to lipidis, glycerol and proteins alone. Glycoproteins are proteins that are post translationally coneected to sugar chains. Mostly the secreted proteins are also glycoslated.
Exocytosis
Golgi bodies are the stacks of membrane that contain energy. They are responsible for packaging proteins to move them outside of the cells.
The rough endoplasmic reticulum (ER) is involved in protein synthesis and transport within the cell. It has ribosomes attached to its surface, which help in the synthesis of proteins that are then transported to other parts of the cell or secreted outside the cell.
