Place the cell structures into the correct order for secretory protein synthesis and export from the cell. That is, once a secretory protein is made, what path will it follow as it is released from the cell?

Answer: 1. ribosome (protein synthesis

2. Rough ER (protein modification)

3. Transport vesicle (protein transport between organelles)

4. Golgi apparatus (protein modification & packaging for secretion)

5. Transport vesicle (protein transport to plasma membrane)

6. Plasma membrane (protein export from the cell)
