Question

Important site for formation of glycoproteins and glycolipids is?

• A. Plastid
• B. Lysosome
• C. Golgi apparatus
• D. Vacuoles

Answer 1

The correct option is C

Golgi apparatus

The correct option is C

Explanation of the correct option:

1. Mucins, a type of glycoprotein present in the body, are released in the mucus of the digestive and respiratory systems.
2. White blood cell recognition depends on glycoproteins.
3. Antibodies, the major histocompatibility complex, gonadotropins, and other immune system components are some examples of glycoproteins.
4. The hormones luteinizing hormone, thyroid-stimulating hormone, erythropoietin, and follicle-stimulating hormone are all glycoproteins.
5. Glycans are added to lipids and proteins by the glycosyl transferase activity of the Golgi apparatus.
6. The Golgi apparatus is where glycolipids and glycoproteins are made.

Explanation of the incorrect option:

Option A:

1. In the cells of plants and algae, there are double-membrane organelles called plastids.
2. Food production and storage are handled by plastids.
3. These frequently include several kinds of pigments that can alter the colour of the cell as well as pigments that are employed in photosynthesis.

Option B:

1. Within eukaryotic animal cells, lysosomes are a crucial cell organelle. They are frequently referred to as the "suicidal bags" of the cell due to their unusual function.
2. Christian de Duve, a Belgian scientist who discovered the word and subsequently won the 1974 Nobel Prize in Physiology or Medicine, is credited with coining it.
3. Hydrolytic enzymes can degrade a wide variety of biomolecules in lysosomes, which are sphere-shaped sacs.

Option D:

1. A membrane-bound cell organelle is known as a vacuole.
2. Animal cells typically have tiny vacuoles that aid in the sequestration of waste.
3. Vacuoles in plant cells aid in preserving the equilibrium of water. A single vacuole may occasionally occupy the majority of a plant cell's inner volume.

Final answer: Important site for the formation of glycoproteins and glycolipids is Golgi apparatus.
