The DNA is contained in the nucleus. The Genes that are needed in the production of antibody are contained in the DNA. The production of antibody begins with the genes of the antibody being transcribed into mRNA this leaves the nucleus by joining on to the ribosome.
Lots of cells secrete proteins into their surrounding extracellular fluid. Some cells like hormones and neurotransmitters secrete regulatory molecules. Whereas others release digestive enzymes, antibodies, or mucus. Fibroblasts secrete collagen are the whole body and other structural proteins to deliver the body with strength and hold the body together.
All proteins are synthesized at cellular structures called ribosomes. When the protein is used in the cell the ribosome stays in the cytosol and the finished protein is released into the cytosol. However if a …show more content…
Then the signal sequence is then cut from the polypeptide chain.
Then the vesicles holding the protein bud from the rough endoplasmic reticulum move too nearby Golgi apparatus. Then the vesicles from the rough endoplasmic reticulum join at one end, adding their proteins to the first flattened vesicle. Then the small vesicle buds from this structure move the proteins to the next layer of the stack. This continues until the protein is on the opposite end of then Golgi apparatus.
After this the vesicles move to the plasma membrane and attach to the membrane and then release their contents off into the extracellular fluid through the process of exocytosis. Sometimes a signal is required to start the release.
Once the protein has moved through the entire Golgi apparatus, secretion vesicles containing the protein bud off. These vesicles move to the plasma membrane, attach to the membrane, and then release their contents into the extracellular fluid through the process of exocytosis. Often a signal is compulsory to initiate the
