The endoplasmic reticulum (ER) is a structure found in eukaryotic cells. It is composed of two parts - the SER and the RER. Which of the following best describes a difference between the RER and the SER. A The rough ER processes toxins, but the smooth ER does not. B The smooth ER is a site of protein synthesis, but the rough ER is not C The rough ER has ribosomes on its surface, but the smooth ER does not. D The smooth ER is part of the endomembrane system, but the rough ER is not.

Which ONE of the following statements is NOT a feature of the endoplasmic reticulum (ER)?Question 13Select one:a.It contains folded layers of membraneb.It is the site where transcription of DNA into mRNA occursc.Parts of the ER are connected to ribosomes, the sites of protein synthesisd.The ER is involved in protein distribution for further processing after synthesis

Regarding rough and smooth endoplasmic reticulum (ER):Group of answer choicesthey are both involved in synthesis of lipidssmooth ER is lined with ribosomesthey are physically connectedrough ER stores calcium

Which ONE of the following statements correctly describes the function of the endoplasmic reticulum (ER) in protein synthesis?Question 12Select one:a.It is the site where new proteins are modified and sorted for export from the cellb.It is the site where transcription of DNA into mRNA occursc.It contains genetic instructions in the form of chromosomesd.It is the membrane network that binds ribosomes during protein translation

Rough endoplasmic reticulum appears "rough" because __________.View Available Hint(s)for Part Amany ribosomes stud the outside of the ER membranethe Golgi apparatus is associated with rough ER to produce proteinslysosomes are attached to the ERof the numerous proteins produced by the rough ER

Eukaryotic cells contain an intricate endomembrane system that includes the nucleus, endoplasmic reticulum (ER), and Golgi complex. The Golgi complex and rough ER are often near each other, which is essential for their roles in the endomembrane system.Which of the following most accurately explains why the Golgi complex is often near the rough ER?Choose 1 answer:Choose 1 answer:(Choice A)   The Golgi complex modifies and packages proteins that are produced in the rough ER.AThe Golgi complex modifies and packages proteins that are produced in the rough ER.(Choice B)   The Golgi complex modifies lipids that have been produced by the rough ER.BThe Golgi complex modifies lipids that have been produced by the rough ER.
