E Correct answer
Explanation

The functions of endoplasmic reticulum are: Detoxification: E.R helps in detoxification of many endogenous and exogenous compounds. Glycogenolysis: Synthesis of glycogen occurs in the cytoplasmic matrix but the SER is involved in glycogenolysis. Lipid synthesis: The SER is concerned with synthesis of lipid e.g. triglyceride. The membranes of SER also appear to be involved in the formation of lipoprotein complexes. The SER is also involved in the initial stages of the breaking down of fatty acids. The nucleoli present in the nucleus helps in the formation of ribosomes.
