What role do vesicles created by the rough endoplasmic reticulum play?

  1. Detoxifying harmful substances

  2. Breaking down large molecules

  3. Carrying new proteins to the Golgi apparatus

  4. Storing water and minerals

The correct answer is: Carrying new proteins to the Golgi apparatus

Vesicles created by the rough endoplasmic reticulum are primarily responsible for transporting newly synthesized proteins to the Golgi apparatus. The rough endoplasmic reticulum is studded with ribosomes, which are the sites of protein synthesis. Once proteins are synthesized within the rough ER, they are enclosed in vesicles that bud off from its membrane. These vesicles then move to the Golgi apparatus, where proteins undergo further processing, sorting, and packaging for their final destinations, such as secretion from the cell or use within the cell. This transport mechanism is crucial for the proper functioning of cellular processes that rely on newly made proteins.
