Question

which of the following correctly shows the sequence of organelles a protein would take if it were being exported from the cell? (1 point)
ribosome → smooth er → vesicle → cell membrane → vesicle → rough er
ribosome → rough er → vesicle → golgi apparatus → vesicle → cell membrane
ribosome → vesicle → rough er → vesicle → golgi apparatus → cell membrane
smooth er → vesicle → golgi apparatus → rough er → vesicle → nucleus

Explanation:

Protein synthesis starts at ribosomes. Ribosomes on the rough endoplasmic reticulum (Rough ER) synthesize proteins. These proteins are then transported in vesicles to the Golgi apparatus for modification and packaging. Finally, vesicles carry the modified proteins to the cell membrane for export.

Answer:

Ribosome → Rough ER → Vesicle → Golgi Apparatus → Vesicle → Cell Membrane
