Show answer and explanation

Answer: B. Synthesis of lipids/steroid hormones and detoxification of drugs/poisons

Answer: B) Synthesis of lipids/steroid hormones and detoxification of drugs/poisons
Explanation: The Smooth Endoplasmic Reticulum (SER) lacks ribosomes. Its main roles are synthesizing lipids, phospholipids, and steroid hormones. In liver cells (hepatocytes), the SER contains specialized enzymes crucial for detoxifying drugs, alcohol, and metabolic wastes.
