Which of the following correctly states the functions of the rough endoplasmic reticulum? a. lipid metabolism, cholesterol synthesis, and synthesis of the lipid components of lipoproteins b. synthesis of cellular membrane components c. absorption, synthesis, and transport of fats d. storage of calcium ions

b. synthesis of cellular membrane components

Explanation:

Endoplasmic reticulum is a network of membranes fistulas; within the cytoplasm of a eukaryotic cells, where proteins and lipids are synthesized usually connected in continuum with the nuclear membrane of the cell.

The ER is of two kinds the smooth and the rough ER (Endoplasmic reticulum).

Functions of Rough endoplasmic reticulum includes; * Synthesis of protein * Degradation of worn out organelles

While the functions of Smooth endoplasmic reticulum includes; * Synthesis of lipid and steroids * Role cellular metabolism * Storage and metabolism of calcium * Catabolism of toxic substance.

Inference from the functions stated above shows that ER is actively involved in the synthesis of cellular membrane components.
