How does the rough endoplasmic reticulum (RER) contribute to protein synthesis and processing?
Understand the Problem
The question is asking about the specific role of the rough endoplasmic reticulum (RER) in protein synthesis and processing. It requires understanding the functions of the RER and how it contributes to the production and modification of proteins.
Answer
The RER facilitates protein synthesis through ribosome attachment, mRNA translation, and protein modification, folding, and sorting.
The rough endoplasmic reticulum (RER) plays a key role in protein synthesis by providing a site for ribosomes to attach and translate mRNA into proteins. It's also involved in post-translational modification, folding, and sorting of proteins.

More Information
The RER's association with ribosomes gives it a 'rough' appearance under a microscope, hence the name.
Tips
A common mistake is to confuse the functions of the rough and smooth endoplasmic reticulum. Remember, the RER is primarily involved in protein synthesis, while the smooth ER is more involved in lipid synthesis and detoxification.
