How can a protein secreting cell synthesize ans secrete its product without the protein ever having to cross a membrane?

Proteins leave to rough endoplasmic reticulum via vesicles that bud off and enter into the Golgi apparatus. Here the proteins undergo further production and some are given cell surface receptors. They then exit the Golgi apparatus via a budding vesicle. That vesicle travels along the microtubules to the plasma membrane, where the vesicle fuses with the plasma membrane. some stay in the membrane as integral proteins and some are released into the area outside of the cell.

What are the types of proteins synthesize in the free ribosome?
Protein synthesis on ribosomes attached to ER membrane: secreted proteins integral membrane proteins soluble proteins destined for life in a membrane bound compartment
How do you separate the inner and outer thylakoid membrane protein?
What is inner membrane protein and outer membrane protein How can you get membrane protein from Ecoli and how to separate the inner and outer membrane protein.
What is attached to membrane systems and scattered in the cytoplasm and synthesize proteins?
Ribosomes. They are the actual site of protein synthesis and float free or are attached to a membranous structure (rough ER) in the cytoplasm.
What do ribosomes make?
Ribosomes synthesize protein.
