Question

Quizplus · Accepted Answer

The endoplasmic reticulum (ER) is a series of membranous tubes and sacs that function in transport, modification, and storage of proteins and lipids. It comes in two types: the smooth ER, which lacks ribosomes and is involved in lipid synthesis and detoxification, and the rough ER, which is studded with ribosomes and is involved in protein synthesis and modification. The description of "tunnel-like membranes" fits the structure of the ER, making choice (E) the correct answer.
