Question

In which of the following organelle glycosylation of proteins and lipids takes place.
a) Vacuole
b) Plastids
c) Lysosome
d) Golgi apparatus

Answer 1

Hint: Glycoproteins are the protein that constitutes the covalently attached sugar is reduced and can change the chemical characteristics of the protein. Glycolipids help in maintaining the stability of the cell membrane and facilitate cellular recognition. They are found in endomembrane organelle that helps in packaging.

Complete answer:
An important site for the formation of glycoproteins and glycolipids in the Golgi apparatus. It is the organelle that is found in eukaryotic cells and packages proteins into membrane-bound vesicles which are found inside the cells. It lies at the intersection of the secretory and endocytic pathway ways which are of particular importance in the processing of proteins for the secretion that contains a set of glycosylation enzymes which get attached to various sugar monomers to proteins. It is a collection of protein products that are received from the endoplasmic reticulum and the protein synthesis in the endoplasmic reticulum are packaged into vesicles that fuse with the Golgi apparatus. The structure of the Golgi apparatus and the function are intimately linked and constitute different assortments of enzymes which allow the progressive processing of the proteins which travel from the cisternae to the trans-Golgi face.

Additional information:
Vacuole: It is a membrane-bound organelle that is filled with water containing inorganic and organic molecules that include enzymes and contains solid in certain cases that have been engulfed.
Plastids: Plastid is a membrane-bound organelle that is found in eukaryotic organisms and considered as endosymbiotic. They are of various types and colors depending upon their functions and storage materials. Plastids are of mainly four types which include chloroplast chromoplast protoplast and leucoplast which is further divided into amyloplast, proteinoplast, and elaioplasts.
Lysosome: Lysosome is a membrane-bound organelle that is involved with various cell processes and helps in the breakdown of excess, worn-out cell parts. It is the suicidal cell organelles of the cell. Lysosomes are the reservoirs of hydrolytic enzymes which are the important enzymes that are acid phosphates, proteases, sulfatases, peptidases, nucleases, and glycosidases. They are structurally spherical vesicles that contain hydrolytic enzymes for The breakdown of biomolecules and have a composition of membrane proteins and lumenal proteins.

So, the correct answer is 'Golgi apparatus'.

Note:
The glycoproteins are involved with the immune system that allows the white blood cells to move around the body and initiates the immune responses which identify other cells. It creates mucus to protect certain organs in our body and are essential for keeping our bodies healthy and functional.
