Question

Which of the following is not a function of Golgi apparatus?
i) Golgi apparatus helps in modifying proteins and lipids.
ii) They secrete mucus.
iii) They help in transporting products into vesicles.
iv) Detoxification of poisons and drugs is a function of smooth endoplasmic reticulum

Answer 1

Hint: Golgi body is also known as Golgi apparatus. It is usually helpful in processing and packaging of protein and lipid molecules. This export and import the protein molecules. It was discovered by Camilo Golgi. The body has a stacked membrane.

Complete answer:
Golgi bodies are found in cytoplasm between endoplasmic reticulum and cell nucleus
Function of Golgi bodies:
1. Golgi bodies help in glycosylation. It is the process of linking carbohydrates with protein that comes from endoplasmic reticulum to form glycoprotein.
2. Golgi bodies form secretory vesicles and help in secretion.
3. They store enzymes and production of hormones.
4. Vacuoles and vesicles which are present in Golgi Complex are major protein lipid storage.
5. They are involved in packing of materials by forming pinocytosis.
6. The secretory vesicles pinch from the end of the cistern and appear as a dense secretory granule in the cytoplasm.
Hence these do not perform Detoxification of poisons and drugs is a function of smooth endoplasmic reticulum.

So, option D is the correct answer.

Note:
The main function of Golgi apparatus is packing and secretion of protein. These proteins are packed into membrane-bound vesicles and then they are transported to various destinations such as lysosomes, plasma membranes etc.
