Question

question 12 of 15
the endomembrane system plays a critical role in eukaryotic cells. which of the following best describes that role?
a. uptake, synthesis, and conversion of glucose and oxygen to carbon dioxide and water.
b. production, processing, and export of newly synthesized polypeptides.
c. production, synthesis, and processing of waste products.
d. detoxification, purification, and export of toxins and drugs.

Explanation:

The endomembrane system in eukaryotic cells is involved in the production, processing, and export of newly synthesized polypeptides. The rough endoplasmic reticulum is associated with ribosomes and synthesizes proteins. The Golgi apparatus modifies, sorts, and packages these proteins for secretion or use within the cell. Option A describes cellular respiration which is mainly done by mitochondria. Option C is incorrect as waste - product processing is not the main role. Option D is not the primary function of the endomembrane system.

Answer:

B. Production, processing, and export of newly synthesized polypeptides.
