NEET BIOLOGY

Detailed explanation-1: -The Golgi apparatus is often found in close proximity to the ER in cells. Protein cargo moves from the ER to the Golgi, is modified within the Golgi, and is then sent to various destinations in the cell, including the lysosomes and the cell surface.

Detailed explanation-2: -The endoplasmic reticulum (ER) plays a key role in the modification of proteins and the synthesis of lipids. It consists of a network of membranous tubules and flattened sacs.

Detailed explanation-3: -The N-linked oligosaccharides of glycoproteins transported from the ER are further modified by an ordered sequence of reactions in the Golgi. The processing of the N-linked oligosaccharide of lysosomal proteins differs from that of secreted and plasma membrane proteins.

Detailed explanation-4: -Golgi bodies receive the proteins produced by the endoplasmic reticulum. It helps in the packaging and transportation of these proteins to various parts of the cell. Hence, it is called the post office of the cell.
