Golgi Apparatus: Cis & Trans Faces — NEET Biology
✅ Asked in NEET 2024The cis and the trans faces of the organelle are entirely different, but interconnected.
The Golgi apparatus has two functionally distinct faces: the cis face (receiving face) where vesicles from ER arrive, and the trans face (shipping face) where processed proteins exit. Although structurally and functionally different, they remain interconnected through a network of tubules and vesicles that facilitate protein transport. Students often confuse which face receives versus ships cargo, leading to wrong answers about protein modification pathways. Remember: cis = entry point (from ER), trans = exit point (to destinations). This concept is critical for understanding secretory pathways and protein synthesis processes tested in NEET.
Given below are two statements: Statement I: The Golgi cisternae are concentrically arranged near the nucleus with distinct convex cis or the forming face and concave trans or the maturing face. Statement II: The cis and trans faces of the organelle are identical and interconnected. Choose the correct answer: NEET 2024
