Question

Quizplus · Accepted Answer

Peptide hormones are often derived from larger precursor molecules called prohormones. They are packaged into secretory vesicles in the Golgi apparatus, not the endoplasmic reticulum, and are typically secreted in response to an increase in cytosolic calcium, not depletion.
