What is the structural difference between smooth and rough endoplasmic reticulum (ER)?
The rough ER has ribosomes attached to its surface, giving it a rough appearance, while the smooth ER lacks ribosomes, resulting in a smooth surface.
What are the functions of the rough endoplasmic reticulum?
The rough ER is involved in protein synthesis and modification, as it has ribosomes on its surface that build proteins.
What are the functions of the smooth endoplasmic reticulum?
The smooth ER is involved in lipid synthesis and detoxification of drugs and poisons.
Which of the following is not a function of the smooth endoplasmic reticulum? A) Lipid synthesis B) Protein synthesis C) Detoxification D) Calcium storage
B) Protein synthesis
Which organelle adds carbohydrate groups to proteins produced at the endoplasmic reticulum?
The Golgi apparatus adds carbohydrate groups to proteins.
How do merocrine exocrine glands secrete their products?
Merocrine exocrine glands secrete their products via exocytosis without losing cellular material.
Which of the following correctly states the functions of the rough endoplasmic reticulum? A) Lipid synthesis B) Protein synthesis C) Detoxification D) Calcium storage
B) Protein synthesis
What occurs during secretion?
Secretion involves the release of substances, such as proteins, into the cell's surroundings.

B) Proteins
How does the function of the rough ER compare to the smooth ER in the cell?
The rough ER is primarily involved in protein synthesis, while the smooth ER is involved in lipid synthesis and detoxification.
