NEET 2023 Phase 2 · BiologyEndomembranePrevious Year Question

Which of the following statements are correct with respect to 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 :

Answer: (D) (A) and (C) only. Answer: (D) (A) and (C) only Solution: (A) is correct — the Golgi apparatus is the important site of formation of glycoproteins and glycolipids; (C) is correct — proteins synthesised by ribosomes on the ER are modified in the Golgi cisternae.

  1. A.(A) and (D) only
  2. B.(D) and (E) only
  3. C.(B) and (C) only
  4. D.(A) and (C) only✓

Correct Answer

(D) (A) and (C) only

Solution & Explanation

Answer: (D) (A) and (C) only Solution: (A) is correct — the Golgi apparatus is the important site of formation of glycoproteins and glycolipids; (C) is correct — proteins synthesised by ribosomes on the ER are modified in the Golgi cisternae. (B) is wrong (ATP is produced by mitochondria, not Golgi), and (D)/(E) (ion transport, mechanical support) are not Golgi functions. So only (A) and (C) are correct. NCERT Reference: Ch 8, p.96, lines 18–22: "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."

BiolGiven below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R). 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. In the light of the above statements, choose the correct answer from the options given below:BiolChoose the correct statements regarding cell organelles and their inclusions. A. The endomembrane system includes Golgi complex, endoplasmic reticulum and mitochondria. B. Rough endoplasmic reticulum bears ribosomes on its surface. C. Both mitochondria and plastids have circular DNA. D. A network of microtubules, microfilaments and intermediate filaments present in the cytoplasm is called cytoskeleton. E. Mitochondrion is a single membrane-bound structure.
