Proteins that are destined to be secreted from the cells must pass through a series of organelles. These organelles include: a. Endoplasmic reticulum b. Golgi apparatus c. Mitochondria d. Lysosomes
Answer: a, b, d Proteins targeted for the secretory pathway most commonly begin with translocation from the cytoplasm across the lipid bilayer into the lumen of the endoplasmic reticulum. It must then pass through a number of compartments including the Golgi apparatus where they are further processed and sorted and end up in a secretory vesicle or lysosome
