What is the primary function of the rough endoplasmic reticulum?
Understand the Problem
The question is asking about the main role or function of the rough endoplasmic reticulum (RER) in a cell. The RER is known for its key role in the synthesis and processing of proteins.
Answer
To produce proteins for the cell.
The primary function of the rough endoplasmic reticulum (RER) is to produce proteins for the cell. The RER is studded with ribosomes, which are essential for protein synthesis.
Answer for screen readers
The primary function of the rough endoplasmic reticulum (RER) is to produce proteins for the cell. The RER is studded with ribosomes, which are essential for protein synthesis.
More Information
The rough endoplasmic reticulum (RER) not only synthesizes proteins but also plays a key role in modifying, folding, and transporting them within the cell.
Tips
A common mistake is confusing the rough endoplasmic reticulum with the smooth endoplasmic reticulum. Remember that the rough ER has ribosomes, making it 'rough' and specialized for protein production.
