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.

Where do proteins move from recticulum?
From the Endoplasmic reticulum, proteins travel to the Golgi Apparatus to be modified and packaged.
How do proteins travel in and out of the cell?
Proteins are so large that they require the interaction of vesicles on cell membranes to get out of cells. Some examples are; enzyme secretion, hormone secretion,neurotransmitter release. Basically they use vesicle formation to get transported into or out of the cell. And since vesicle forming is an energy requiring process it would be an exocytosis or endocytosis reaction. But usually as an even simpler answer, cells do not usually take in proteins, they take in amino acids which then make their own proteins.
How do horomones travel throughout the body?
This depends whether the hormone is an EXOcrine hormone or an ENDOcrine hormone. EXOcrine hormones are secreted into a hollow cavity or the exterior to have a direct effect. I.e gastric hormones being secreted directly into the stomach to digest food. ENDOcrine hormone are secreted directly into the bloodstream to be carried to their target receptors and cells
What happens to proteins with in the endoplasmic reticulum?
Newly made proteins are either released into the cytoplasm or transported into the rough endoplasmic reticulum. Those released into the cytoplasm may make their way into the nucleus if they have the nuclear localisation signal. Proteins that contain an N terminal signal sequence in their amino acid sequence will be transported into the rough endoplasmic reticulum or the RER membrane, where they will undergo further processing (mainly glycosylation) before vesicular transport to an organelle or the cell membrane.
Is the smooth er important and why?
it is the"road" by which proteins travel. smooth endoplasmic reticulum has no ribosomes, but is still important in carrying proteins

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.
How is the Proteins that are secreted from a eukaryotic cell must first travel through the endomembrane system set up?
As they are being synthesized, secretory proteins enter the lumen of the endoplasmic reticulum. From the ER, vesicles transport these proteins to the Golgi, where they are sequentially modified and concentrated in a cis-to-trans direction. Secretory vesicles bud from the Golgi and move along cytoskeletal filaments to eventually fuse with the plasma membrane, secreting their protein cargo. Each of these transport steps requires specialized proteins to ensure that the cargo is sent to the proper location and is able to fuse with the target membrane.
Does email travel in packets?
Yes it does. Everything that is transmitted over the internet is packaged.

How do proteins travel in the blood?
can you tell me how youtransport protein please
Does American Airlines have flights to Bogota?
American Airlines does have several airplane flights, as well as packaged travel plans, travel brochures, and tourist destinations, for Bogota, Columbia.

How are proteins trasported from the nuclear membrane to other parts of the cell?
the proteins travel through the cell by the endoplasmic reticulum(ER).
