What is the main role of the endoplasmic reticulum?

Carbohydrate synthesis
Gas exchange
Lipid synthesis
Protein synthesis

The correct answer is: Protein synthesis

The endoplasmic reticulum is an organelle found in eukaryotic cells that plays a critical role in protein synthesis. It is responsible for folding, modifying, and transporting newly synthesized proteins to their proper destination within the cell. Option A, carbohydrate synthesis, is incorrect because that is the role of the chloroplast in plants and the mitochondrion in animals. Option B, gas exchange, is incorrect because that is the main function of the respiratory system. Option C, lipid synthesis, is incorrect because that is the role of the smooth endoplasmic reticulum, a subtype of the endoplasmic reticulum. The main role of the endoplasmic reticulum is protein synthesis.
