DNA replication
C
ATP production
D
Protein synthesis
Verified step by step guidance1
Understand the structure of the endoplasmic reticulum (ER) in eukaryotic cells, which is divided into two types: rough ER and smooth ER.
Recognize that the rough ER is associated with ribosomes and is primarily involved in protein synthesis.
Identify that the smooth ER lacks ribosomes on its surface, which differentiates its function from the rough ER.
Learn that the smooth ER is primarily involved in the synthesis of lipids, including phospholipids and steroids, which are essential for cell membrane structure and function.
Note that the smooth ER also plays a role in detoxification processes and calcium ion storage, but its primary function is lipid synthesis.
