The Endoplasmic Reticulum

Lipid synthesis primarily involves enzymes located in the endoplasmic reticulum (ER). These enzymes include fatty acid synthase, which synthesizes fatty acids, and enzymes involved in glycerolipid and phospholipid synthesis. In addition, the synthesis of membrane or secreted proteins involves ribosomes attached to the ER, where these proteins are synthesized and processed before being transported to their target destinations.

What happens after the synthesis of proteins?
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.
Glycoproteins are membrane proteins?
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.
Which organelle is a network of membranes involved in the production of proteins that will become secreted of part of the plasma membrane?
The rough endoplasmic reticulum is a network of membranes involved in the production of proteins. Protein synthesis occurs in the ribosomes, which are attached to the outside of the rough ER, giving it a 'rough' appearance.
What receives newly synthesized proteins?
Most of the proteins that are being synthesized come from the ribosomes attached to the rough endoplasmic reticulum (ER). After the protein synthesis is completed, the new protein molecule goes into the ER in order to complete their synthesis (sometimes it has to be passed through a process called "post-translational modification", e.g., the addition of a carbohydrate residue) that is taking place in the lumen of the ER. Afterwards, the complete protein (if it has to be secreted) goes to the Golgi apparatus and to the plasma membrane.
Where do proteins travel to get modified packaged and secreted?
Many proteins must be chemically folded into an active tertiary structure. The protein must be transported to where it will function. Sometimes the protein must move out of the cell, as in the case of hormones such as insulin. In such case, a small membrane vesicle contains the protein fuses with the cell membrane. The protein is than released outside and the proteins that are destined to become a part of membrane are made on ribosomes that are bound to the endoplasmic reticulum.
What are the types of proteins synthesize in the free ribosome?
Protein synthesis on ribosomes attached to ER membrane: secreted proteins integral membrane proteins soluble proteins destined for life in a membrane bound compartment

What is the role of the liver in protein metabolism?
The liver produces the proteins that are secreted into the blood. The liver is responsible for protein metabolism, degradation and synthesis

What macromolecule is assembled and secreted by the smooth endoplasmic?
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.

Where materials contining energy are packaged and secreted?
Golgi bodies are the stacks of membrane that contain energy. They are responsible for packaging proteins to move them outside of the cells.
What is the process by which newly made proteins are secreted out of an animal cell?
Which is the process by which newly-made proteins are secreted out of an animal cell?
What is the rough endoplasmic recticulum?
It's an organelle of the cell attached to the outer nuclear membrane. In contrast to the smooth endoplasmatic reticulum (SER), the RER is seeded with ribosomes on its membranes. These ribosomes produce proteins which are either transported inside the RER, or incorporated in the RER-membrane. Parts of this membrane will come loose of the RER and be transported to the Golgi complex and afterwards to the cell membrane or other organelles. This way, proteins inside the RER can eventually be secreted, and proteins in the membrane can end up in the cell membrane.
Where are proteins made in the cell?
Depending on where the protein will end up, it will either be made by ribosomes in the cytoplasm (proteins that are to remain soluble in the cell) or ribosomes docked on the endoplasmic reticulum (proteins that will be secreted out of the cell, incorporated into the plasma membrane, proteins that will end up in the endoplasmic reticulum and/or Golgi complex).
Where travel proteins?
Cellular (transported) proteins travels around the cell and sometimes destined to the particular organelle where it does its function. Secreted proteins such as albumin or hemogolbin are carrier proteins. Hemoglobin carries oxygen and carbon dioxide all over the body through blood tissue.
