processing of peptide hormones - ️️1. preprohormones are synthesized from rER and migrate to Golgi in membrane bound vesicles 2. while in ER and golgi, preprohormones are processed into prohormones followed by active hormones 3. golgi packages and labels hormones into secretory vesicles that are stored in cytoplasm until appropriate signal 4. upon signal, vesicle membrane fuses with plasma membrane and peptide hormone is exocytosed major processes the endocrine system can regulate in...
