Question

Quizplus · Accepted Answer

Proteins that are transported in vesicles are generally produced by ribosomes on the rough endoplasmic reticulum, which is involved in protein synthesis, modification, and transportation. The Golgi apparatus helps to sort, modify, and package proteins into vesicles for transportation to their final destination. The smooth endoplasmic reticulum, on the other hand, is involved in lipid synthesis and detoxification of drugs and toxins. Ribosomes within mitochondria and chloroplasts are responsible for producing proteins that are specific to those organelles.
