Question

according to the endosymbiotic theory, infoldings in the cell membrane of an ancestral prokaryotic cell gave rise to endomembrane components, including the nucleus, endoplasmic reticulum and golgi apparatus in what would become eukaryotic cells. the evolution of endomembrane components provided for compartmentalization in eukaryotes, leading to more efficiency in cell processes. which part of the endomembrane system provides a mechanism for transporting proteins from the rough er to the golgi apparatus? a vesicle b lysosome c smooth er d peroxisome

Explanation:

Vesicles are small membrane - bound sacs that transport materials within the cell. They bud off from the rough endoplasmic reticulum (ER) and carry proteins to the Golgi apparatus. Lysosomes are involved in digestion, smooth ER is mainly for lipid synthesis and detoxification, and peroxisomes are involved in breaking down fatty acids and hydrogen peroxide.

Answer:

A. vesicle
