Proteins that are trafficked through the secretory pathway of eukaryotic cells are never exposed directly to the cytoplasm. Which of the following is the best explanation for why this is true? A. Cells that specialize in protein secretion lack cytoplasm, because protein synthesis machinery takes up the volume of the cell instead. B. For a protein that will be secreted, during the whole time that it spends inside of the cell, it is enclosed within other membrane-bound compartments. C. While a protein is in the secretory pathway, it is surrounded by a dense cloud of ions that protect it from the cytoplasm. D. A protein that will be secreted is not synthesized by ribosomes in the cytoplasm; instead, it is synthesized by proteins at the plasma membrane and fed directly into the extracellular space.
