Golgi Apparatus: Packaging & Modification — NEET Biology
✅ Asked in NEET 2025The golgi apparatus principally performs the function of packaging materials, to be delivered either to the intra-cellular targets or secreted outside the cell. Materials to be packaged in the form of vesicles from the ER fuse with the cis face of the golgi apparatus and move towards the maturing face. This explains, why the golgi apparatus remains in close association with the endoplasmic reticulum. A number of proteins synthesised by ribosomes on the endoplasmic reticulum are modified in the cisternae of the golgi apparatus before they are released from its trans face. Golgi apparatus is the important site of formation of glycoproteins and glycolipids.
The Golgi apparatus receives vesicles from the ER at its cis face, modifies proteins and lipids in its cisternae, and releases them from the trans face for secretion or internal delivery. NTA frequently tests whether students know the directional movement (cis → trans) and that Golgi modifies (not just packages) materials through glycosylation. Common mistakes: confusing cis and trans faces, thinking Golgi only packages without modifying, or forgetting that proteins from ribosomes on rough ER are the source material. Remember: Golgi is a modification and sorting factory—vesicles enter at cis (receiving face) and exit at trans (shipping face), with protein modification happening in between cisternae.

Given below are two statements: Assertion (A): The primary function of the Golgi apparatus is to package the materials made by the endoplasmic reticulum and deliver it to intracellular targets and outside the cell. Reason (R): Vesicles containing materials made by the endoplasmic reticulum fuse with the cis face of the Golgi apparatus, and they are modified and released from the trans face of the Golgi apparatus.

Given below are two statements: Statement I: Concentrically arranged cisternae of Golgi complex are arranged near the nucleus with distinct convex cis or forming face and concave trans or maturing face. Statement II: A number of proteins are modified in the cisternae of Golgi complex before they are released from the cis face. NEET 2024
