Protein synthesis — practice question

A cell takes in amino acids. It then makes and releases a digestive enzyme. Several cell structures take part in the different stages of this process. Which row shows a possible order of the cell structures through which the amino acids move?

  • Acell surface membrane: 1st; Golgi body: 2nd; rough endoplasmic reticulum: 3rd; secretory vesicle: 4th
  • Bcell surface membrane: 1st; Golgi body: 3rd; rough endoplasmic reticulum: 4th; secretory vesicle: 2nd
  • Ccell surface membrane: 4th; Golgi body: 2nd; rough endoplasmic reticulum: 1st; secretory vesicle: 3rd
  • Dcell surface membrane: 4th; Golgi body: 1st; rough endoplasmic reticulum: 2nd; secretory vesicle: 3rd
