It is found that a particular type of cell isolated and growing in culture secretes a much larger amount of protein than human liver cells grown under the same conditions.From this, you hypothesize that these cells must have a large number or amount of
A) rough endoplasmic reticulum.
B) smooth endoplasmic reticulum.
C) chromosomes.
D) nuclear pores.
E) peptidoglycan.

Question

Quizplus · Accepted Answer

Protein synthesis is one of the primary functions of the rough endoplasmic reticulum (ER) in eukaryotic cells. If a particular type of cell secretes a much larger amount of protein than other cells grown under the same conditions, it suggests that this cell type has a greater abundance of rough ER, which is responsible for the translation and secretion of proteins. The smooth ER is not directly involved in protein synthesis and would not account for the increased protein secretion observed in this cell culture. Chromosomes, nuclear pores, and peptidoglycan are not directly related to protein synthesis and secretion in eukaryotic cells.
