Verified step by step guidance

Understand the structure of the rough endoplasmic reticulum (RER): The RER is characterized by the presence of ribosomes on its surface, giving it a 'rough' appearance under a microscope.

Recognize the role of ribosomes: Ribosomes are the cellular machinery responsible for synthesizing proteins by translating messenger RNA (mRNA) into polypeptide chains.

Connect ribosomes to the RER: The ribosomes attached to the RER are involved in synthesizing proteins that are either secreted from the cell, incorporated into the cell's plasma membrane, or used within lysosomes.

Identify the process of protein synthesis: Proteins synthesized by ribosomes on the RER are processed within the RER, where they undergo folding and modifications such as glycosylation.

Summarize the primary function: The rough endoplasmic reticulum is primarily involved in the synthesis and processing of proteins, distinguishing it from other cellular structures involved in lipid synthesis, genetic storage, or ATP production.
