How does the function of the rough endoplasmic reticulum (ER) compare to the smooth endoplasmic reticulum (ER) in the cell?
A
The rough ER is involved in detoxification, while the smooth ER is involved in protein folding.
B
The rough ER is involved in protein synthesis, while the smooth ER is involved in lipid synthesis and detoxification.
C
Both the rough and smooth ER are primarily involved in carbohydrate metabolism.
D
The rough ER is responsible for lipid synthesis, while the smooth ER is responsible for protein synthesis.
검증된 단계별 안내1
Understand the structure of the endoplasmic reticulum (ER): The ER is a network of membranes within the cell, and it comes in two forms - rough and smooth.
Identify the rough ER: The rough ER is studded with ribosomes on its surface, which gives it a 'rough' appearance under a microscope.
Determine the function of the rough ER: The presence of ribosomes indicates that the rough ER is primarily involved in protein synthesis. Ribosomes are the sites where amino acids are assembled into proteins.
Identify the smooth ER: The smooth ER lacks ribosomes, giving it a 'smooth' appearance.
Determine the function of the smooth ER: The smooth ER is involved in lipid synthesis, detoxification processes, and carbohydrate metabolism. It plays a role in synthesizing lipids and steroids, metabolizing carbohydrates, and detoxifying drugs and poisons.
