Which type of endoplasmic reticulum is primarily involved in the synthesis and processing of secretory proteins?
Understand the Problem
The question is asking about the specific type of endoplasmic reticulum that plays a key role in the synthesis and processing of secretory proteins, which requires knowledge of cell biology.
Answer
Rough endoplasmic reticulum.
The rough endoplasmic reticulum is primarily involved in the synthesis and processing of secretory proteins.
Answer for screen readers
The rough endoplasmic reticulum is primarily involved in the synthesis and processing of secretory proteins.
More Information
The rough endoplasmic reticulum, distinguished by the presence of ribosomes on its surface, plays a central role in synthesizing proteins destined for secretion or incorporation into the cell membrane. These ribosomes give the ER a 'rough' appearance.
Tips
A common mistake is confusing the rough endoplasmic reticulum with the smooth endoplasmic reticulum, which is involved in lipid synthesis and lacks ribosomes.
