Question

Quizplus · Accepted Answer

The endoplasmic reticulum (ER) is a series of tunnel-like membranes within the cytoplasm of eukaryotic cells. It functions in transport and storage of proteins and other molecules. There are two types of ER: smooth and rough. The rough ER is covered in ribosomes and involved in the synthesis and processing of proteins. The smooth ER lacks ribosomes and is involved in lipid metabolism and detoxification of drugs and poisons.
