An endocrine cell that contains an abundance of granular endoplasmic reticulum,a large Golgi apparatus,and secretion granules is likely to secrete a peptide hormone.

Question

Quizplus · Accepted Answer

Peptide hormones are synthesized on ribosomes and then processed in the granular endoplasmic reticulum and Golgi apparatus before being packaged into secretion granules for release. Therefore, an endocrine cell with abundant granular endoplasmic reticulum, a large Golgi apparatus, and secretion granules is likely to be secreting a peptide hormone.
