Question

Which cell organelle plays a crucial role in detoxifying many poisons and drugs in a cell?

• A. Golgi apparatus
• B. Lysosomes
• C. Smooth endoplasmic reticulum
• D. Vacuoles

Answer 1

The correct option is C

Smooth endoplasmic reticulum

The correct option is C.

Explanation of the correct option:

1. Smooth endoplasmic reticulum (SER) is a part of the endoplasmic reticulum which does not have ribosomes studded on its membrane.
2. It is involved in the detoxification of many poisons and drugs such as drugs, insecticides (DDT), petroleum products, and pollutants and converting them to safer water-soluble products.
3. Endoplasmic reticulum (ER) helps in the synthesis of protein and phospholipids.
4. As ER are of two types, Rough endoplasmic reticulum, and Smooth endoplasmic reticulum.
5. The smooth endoplasmic reticulum synthesizes phospholipids.

Explanation of the incorrect options:

Option A:

1. Golgi body is the membrane-bound flattened sac-like structure.
2. There are different functions that are performed by Golgi such as modification, sorting, and packaging of the proteins, which are synthesized by cells.

Option B:

1. Lysosome is the cell organelle that digests the intracellular food particles.
2. It cleans the cell by digesting damaged materials.
3. Sometimes lysosomes eat their own cell so the cell can lead to death.

Option D:

1. Vacuole stores substances like harmful waste or useful material.
2. It also maintains a water balance in the cell.
3. Vacuole stores salts, minerals, pigments, and proteins within the cell.

Final answer: Smooth endoplasmic reticulum is a cell organelle which plays a crucial role in detoxifying many poisons and drugs in a cell.
