production of proteins

• What is the first step of proteins being produced and secreted?

  polypeptide chains are synthesized on the rough endoplastic reticulum
• What is the second step of proteins being produced and secreted?

  The previously produced polypeptide chains move to the cisternae in the rough endoplastic reticulum and are packed into vesicles to be sent to the golgi apparatus via the cytoskeleton
• what is the third step of proteins being produced and secreted?

  In the golgi apparatus,the proteins are modified and packaged into vesicles
• what is the fourth step of proteins being produced and secreted?


  The secretory vesicles carry the proteins to the cell surface where it fuses and releases the protein via exocytosis.
