Describe how a cell produces and releases proteins.
Answer (3)
The cell produces proteins by process called translation. Proteins the moved to endoplasmic and later on they are releases by exocytosis.
Cells produce and release proteins by transcribing DNA into mRNA, translating mRNA on ribosomes to synthesize proteins, modifying them in the Golgi apparatus and then using vesicles to either deliver proteins within the cell or secrete them outside via exocytosis.
The process by which a cell produces and releases proteins involves several steps. Firstly, the information to produce a protein is encoded in the cell's DNA. The cell transcribes this information into messenger RNA (mRNA), which then travels to a ribosome. The ribosome reads the mRNA and assembles amino acids into a protein. If the protein is to be used within the cell, it will be synthesized by a free-floating ribosome. However, if the protein is destined for the lysosome, the plasma membrane, or to be secreted, it is made on a ribosome attached to the rough endoplasmic reticulum (RER).
After synthesis, the protein is packaged into a vesicle that moves to the Golgi apparatus where it is modified. The final modified protein exits the Golgi in a vesicle, which either delivers it to its cellular destination or fuses with the plasma membrane to secrete the protein outside the cell, a process known as exocytosis. This entire pathway is essential for the production and release of proteins in a cell.
Cells produce proteins through transcription of DNA to mRNA and translation of mRNA to amino acids at ribosomes. After post-translational modifications, proteins are transported to the Golgi apparatus for sorting. Finally, proteins are released from the cell through exocytosis.
