Question

Which of the following is not a function of Golgi apparatus?

• A. Golgi apparatus helps in modifying proteins and lipids.
• B. They secrete mucus.
• C. They help in transporting products into vesicles.
• D. Detoxification of poisons and drugs

Answer 1

The correct option is D

Detoxification of poisons and drugs

The correct option is D.

The explanation for the correct option:

1. The endoplasmic reticulum is an organelle found within the eukaryotes, which comes in two forms, that is, it can be either smooth or rough.
2. The absence of membrane-bound ribosomes makes the endoplasmic reticulum smooth.
3. Ribosomes are the intercellular composition formed of both protein and RNA and are the site of the synthesis of protein within the cell.
4. The smooth endoplasmic reticulum does several metabolic processes as it helps in the synthesis of lipids and steroid hormones.
5. Apart from this, it detoxifies harmful components like drugs and toxins from the cells.

The explanation for the incorrect options:

Option A:

1. The Golgi body is also known as the Golgi apparatus, was discovered by Camilo Golgi.
2. Its prime role is to process and package the molecules of lipids and proteins.
3. Golgi apparatus is an organelle having a stacked membrane and is found within the eukaryotes.
4. Thus, the Golgi apparatus assists in modifying lipids and proteins.

Option B:

1. Golgi apparatus are secretory, therefore, they secrete mucus.

Option C:

1. The prime function of the Golgi apparatus is the secretion and packaging of proteins and lipids.
2. The lipids and proteins are packed into membrane-bound vesicles and are transported to different destinations like plasma membranes, lysosomes, etc.

Final answer: Detoxification of poisons and drugs is not a function of the Golgi apparatus.
