The correct relationship between ribosomes and rough endoplasmic reticulum (ER) is that ribosomes attached to rough ER make proteins that the rough ER then transports around the cell.
The correct answer is: "Ribosomes attached to rough ER make proteins that the rough ER then transports around the cell."
Explanation: Ribosomes are the cellular structures responsible for protein synthesis. They are composed of two subunits, one large and one small, and can be found either freely distributed within the cytoplasm or attached to the rough endoplasmic reticulum (ER).
When ribosomes are attached to the rough ER, they synthesize proteins directly into the ER lumen (interior). As the proteins are being synthesized, they are threaded into the ER lumen for proper folding and processing. The rough ER acts as a site of protein synthesis and modification, specifically for proteins that need to be transported outside the cell or to other organelles.
Once the proteins are processed and folded within the rough ER, they are then transported to their destinations via vesicles. In the case of proteins synthesized by ribosomes attached to the rough ER, these proteins are primarily destined for secretion or for delivery to other organelles, such as the Golgi apparatus.
Therefore, the relationship between ribosomes and rough ER is that the ribosomes attached to rough ER synthesize proteins, which are then transported by the rough ER to their proper locations within the cell.
