Final answer:
Peptide neurotransmitters are synthesized in certain neurons and need to be shipped to the cell surface for release. The organelles involved in their synthesis and transportation include ribosomes, endoplasmic reticulum, Golgi apparatus, and the secretory pathway.
Step-by-step explanation:
Peptide neurotransmitters are synthesized by some neurons. Organelles in abundance to manufacture these proteins would include ribosomes and endoplasmic reticulum.
These neurotransmitters would need to be shipped to the cell surface. They would leave in vesicles from the Golgi apparatus and travel along the secretory pathway to reach the cell's surface.
