13. Intracellular Protein Transport

What is the primary function of vesicles in eukaryotic cells?

In the context of vesicular budding, transport, and coat proteins, which organelle is primarily responsible for sorting, modifying, and packaging proteins into transport vesicles for delivery to different cellular destinations?

In the context of vesicular budding, transport, and coat proteins, what is the primary mechanism that transports newly synthesized proteins between organelles such as the ER and Golgi within the cell?
