Secretory protein:

Some proteins are synthesized in cells and secreted outside the cell. such as digestive enzymes, antibodies and a portion of hormones.

Secretory protein synthesis Process:

Secreted proteins are initially peptide chains that have amino acids in the ribosomes on the endoplasmic web.

The peptide chain enters the endoplasmic reticulum for processing and forms a protein with a certain spatial structure .

endoplasmic reticulum can "sprout", that is, the bulge formed by the membrane vesicles, wrapped in the protein to transport, leaving the endoplasmic reticulum. Reach Golgi.

After the protein is combined with the Golgi body membrane, the vesicle membrane forms part of the Golgi membrane. The Golgi body can also process proteins into one step , and then form vesicles that wrap the protein.

The vesicles move to the cell membranes and are fused with the cell membranes to secrete proteins out of the cell.

(In the synthesis, processing and transport of secretory proteins, energy from the mitochondria is needed.) )

Inside the cell, many membranes of vesicles are like submarines in the deep sea, shuttling through the cells, transporting "cargo" in a busy manner, while Golgi plays an important role in the transport hub.
