Proteins are produced in the cytoplasm, in the rough endoplasmic reticulum, in mitochondria, and in chloroplasts.
Proteins consist of one or more polypeptide chains. Polypeptides are synthesized by ribosomes as they travel along strands of messenger RNA. This synthesis begins at free (unattached) ribosomes in the cytoplasm, but as it proceeds some ribosomes are moved to the rough endoplasmic reticulum and embedded in its membrane. Whether a ribosome is moved depends on the sequence of amino acids in the first part of the polypeptide chain to be translated. The polypeptides that are produced in the endoplasmic reticulum complete their coiling and folding (secondary and tertiary structure) within the lumen of the endoplasmic reticulum, where some of them will also combine with other chains to form more complex proteins (quaternary structure). Proteins synthesized in the rough endoplasmic reticulum are destined for certain sites, e.g. the endoplasmic reticulum itself, lysosomes, the plasma membrane, or for secretion from the cell. Those that are leaving the endoplasmic reticulum pass through the Golgi body, where they may be further processed, e.g. with the addition of oligosaccharide components. Proteins whose synthesis is completed in the cytoplasm at free ribosomes go to other destinations, such as the nucleus, mitochondria, and chloroplasts. The mitochondria and chloroplasts, which are thought to be descendants of ancient free-living prokaryotic cells, have some genes of their own and synthesize some proteins using their own transcription and translation machinery, including their own (prokaryote-like) ribosomes.
What else can I help you with?
What is produced by all cells?
Energy, waste products, and proteins are produced by all cells.
Does proteins have cells?
Proteins are biomolecules made up of amino acids and are synthesized by cells. Proteins play many vital roles in cells, such as structural support, catalyzing biochemical reactions, and cell signaling. While proteins themselves do not have cells, they are essential components of all living cells.
Explain briefly how cells make proteins?
Proteins are produced in the mitochondria with ribosomes that are produced by the nucleoli in the nucleus of a cell.
What is the name of the Proteins that are produced by cells and act as catalysts?
Proteins that are catalysts are called enzymes. A majority of enzymes are proteins, though not all.
Why are proteolytic enzymes produced in an inactive form?
Proteolytic enzymes will destroy the cells that produced them if they are produced in an active form. To protect the body's own cells these enzymes are secreted in an inactive form into the digestive tract and activated where they are needed.
What is produced by all cells?
Energy, waste products, and proteins are produced by all cells.
Which of the types of cells display protein fragments produced by the cancer within them?
All nucleated cells bring pieces of endogenous proteins to the surface to display on the MHC protein.

Where within a cell are proteins produced?
Ribosomes... :D

Proteins that are catalysts are called enzymes. A majority of enzymes are proteins, though not all.
Where within a cell are catalyst synthesized?
Enzymes are natural catalysts produced by cells, and all enzymes are proteins made in the cytoplasm of the cell by translation of genetic material (mRNA).
Does chromosome have cells?
No, chromosomes do not have cells. Chromosomes are made up of DNA and proteins and are found within cells.
Why are proteolytic enzymes produced in an inactive form?
Proteolytic enzymes will destroy the cells that produced them if they are produced in an active form. To protect the body's own cells these enzymes are secreted in an inactive form into the digestive tract and activated where they are needed.
What protein is produced during photosynthesis?
The protein produced during photosynthesis is called RuBisCO (ribulose-1,5-bisphosphate carboxylase/oxygenase), which plays a key role in fixing carbon dioxide from the atmosphere into organic molecules within the chloroplasts of plant cells.
What are the final products of proteins?
In prokaryotic cells, mRNA is directly produced. In eukaryotic cells, the first product is called the primary transcript.
What structures in which proteins are manufactured?
Basically proteins are not manufactured, but produced by living cells. But proteins can then be modified chemically, splitted and recomposed in a lot of ways industrially for specific purposes.
