Which one of the following functions is not carried out by smooth endoplasmic reticulum?
General KnowledgeBiology
- ATransport of materials
- BSynthesis of lipid
- CSynthesis of protein
- DSynthesis of steroid hormone
Explanation
The smooth endoplasmic reticulum synthesises lipids and steroid hormones and transports materials within the cell. Protein synthesis is carried out by ribosomes on the rough endoplasmic reticulum, not by the smooth ER. Hence the function not carried out by smooth ER is the synthesis of protein. Hence option C is correct.
