Which organelle in eukaryotic cells is responsible for the metabolism of xenobiotics and contains enzymes like cytochrome P450?
Correct: B
Smooth Endoplasmic Reticulum (SER) is specialized for lipid synthesis and detoxification processes, housing enzymes like cytochrome P450 that metabolize drugs and toxins. Rough ER contains ribosomes for protein synthesis, Golgi modifies proteins, and mitochondria handle energy production.
