Which of the following statements are correct with respect of Golgi apparatus ?
(A) It is the important site of formation of glycoprotein and glycolipids.
(B) It produces cellular energy in the form of ATP.
(C) It modifies the protein synthesized by ribosomes on ER.
(D) It facilitates the transport of ions.
(E) It provides mechanical support.
Choose the most appropriate answer from the options given below :

(A) and (C) are correct. (B), (D) and (E) are incorrect. 
A. Statement A is correct. Glycoproteins and glycolipids are formed by addition of carbohydrate groups to proteins and
lipids, respectively. Golgi is the site of this glycosylation process. 
B. Statement B is incorrect. ATP production primarily occurs in the mitochondria, not the Golgi apparatus. 
C. Statement C is correct. Golgi body modifies the proteins synthesised by ribosomes on the endoplasmic reticulum (ER). The Golgi apparatus receives proteins synthesised on the ribosomes of the ER and modifies them. This modifi cation includes processes, like adding sugar moieties, cleaving signal peptides, and folding the proteins into their functional conformation.
D. Statement D is incorrect. While the Golgi apparatus is involved in intracellular transport, it does not primarily facilitate the transport of ions. It mainly deals with the transport and sorting of proteins and lipids.
E. Statement E is incorrect. The Golgi apparatus does not provide mechanical support. The cytoskeleton, which is composed of proteins such as microtubules and microfilaments, is responsible for providing structural support to the cell.
