At this point the procollagen is packaged into a transfer vesicle destined for the golgi apparatus.

For example, clathrin-coated vesicles transport substances between the golgi apparatus and the plasma membrane.

Some of these small vesicles contain cisternae with ribosomes and are found located near the golgi apparatus.

Secondly, the triple helix known as procollagen is formed before being transported in a transport vesicle to the golgi apparatus.

These models were mostly approved for demonstrating how endoplasmic reticulum, golgi apparatus, nuclear membrane, and single membrane structures such as lysosomes came into being.
