Answer:
peptide and protein hormone
Explanation:
Peptide and protein hormones are composed of amino acids with latter being longer in length. They are synthesized in rough endoplasmic reticulum where they undergo various modifications like N terminal signal sequence removal and glycosylation to form prohormones. These prohormones are sent to golgi apparatus where they are packaged in secretory vesicles. In response to a stimulus the appropriate vesicle is released via exocytosis.
They can show regulated secretion where the hormone is stored in vesicles for a long time and then released in large amount in bursts for a proper stimulus. Sometimes they also show constitutive secretion where they are released slowly and steadily by the vesicles.
