Solution
Correct Answer:
Protein translation for secretion
- Distinction: The Endoplasmic Reticulum (ER) is divided into Rough (RER) and Smooth (SER).
- Rough ER (RER): It is 'rough' because it is studded with ribosomes on its outer surface.
- Function: These ribosomes are the sites for the translation (synthesis) of proteins that are destined for secretion out of the cell, for incorporation into the cell membrane, or for lysosomal enzymes.
- Smooth ER (SER): It lacks ribosomes and is primarily involved in lipid and steroid synthesis, as well as the detoxification of drugs and poisons.
This medium difficulty biology question is from the chapter cell structure and function, covering the topic of endoplasmic reticulum. It appeared in the 2025 exam.
