Which Organelle is a Network of Membranes Involved in the Production

Question

Which organelle is a network of membranes involved in the production of proteins?
A) chloroplast
B) endoplasmic reticulum
C) lysosome
D) nucleus

Accepted Answer

The endoplasmic reticulum (ER) is a network of membranes that is responsible for protein synthesis and folding. The rough ER is studded with ribosomes, which are involved in the production of proteins. The smooth ER is involved in lipid synthesis and detoxification. Chloroplasts are involved in photosynthesis, lysosomes contain digestive enzymes, and the nucleus contains genetic material.
