Protein synthesis happens in the cytoplasm in special organelles called ribosomes.
Proteins are manufactured in the cell at the ribosomes, which are the organelles responsible for protein synthesis.
The DNA molecule carries genetic recipes for proteins. Proteins are manufactured in the ribosomes within the cell and are integral in most cell activities.
The Golgi apparatus is responsible for modifying proteins and lipids after they are manufactured. It receives proteins and lipids from the endoplasmic reticulum, modifies them by adding sugars and lipids, and then packages them into vesicles for transportation to their final destination within or outside the cell.
During G 1 phase, the cell grows in size and synthesizes mRNA and proteins that are required for DNA synthesis Cytoplasm is 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.
Ribosome
Ribosomes are the cell organelles that assemble proteins. They function as factories to produce usable proteins for a cell.
Defensive proteins are manufactured by the immune system. The immune system is the system of biological structures and processes in the body that protects against disease.
There are two kinds of proteins in a cell membrane: peripheral PROTEINS OR trans membrane proteins. Cell membranes are able to perform various functions only because of different membrane protein functions. Most of the membrane proteins have alpha helix structure.
Defensive proteins are manufactured by the immune system. These proteins help protect the body from pathogens such as bacteria and viruses. Examples include antibodies and cytokines.
The proteins that control reaction in a cell are enzymes.
Ribosomal proteins are synthesized in the cytoplasm of the cell.
