Smooth endoplasmic reticulum is especially abundant in liver cells because it is the site of
Correct answer: A. detoxification of drugs and poisons
- A. detoxification of drugs and poisons
- B. synthesis of proteins for export
- C. production of most of the cell's ATP
- D. digestion of worn out organelles
Explanation
The smooth ER carries the enzymes that break down drugs, alcohol and metabolic poisons, which is why liver cells are rich in it. Protein export depends on rough ER, ATP on mitochondria, and digestion of organelles on lysosomes.

About Animal and Plant Cell
Animal and plant cells share a plasma membrane, cytoplasm, nucleus, ribosomes, mitochondria and endoplasmic reticulum, but plant cells also have a cellulose cell wall, chloroplasts and a large permanent vacuole. Questions cover organelle structure and function, differences between the two cell types, and how membranes control movement of substances.
