SSC GD 2025 PYQ — Question 33

The correct answer is option 4 i.e. Mitochondria - Lipid metabolism.

• Mitochondria - Lipid metabolism is NOT correctly matched.
• The primary function of the Mitochondria is cellular respiration (or energy production), generating ATP (adenosine triphosphate).
• While mitochondria are involved in some aspects of lipid metabolism, their most distinct and defining function is generating energy.
• Much of the cell's lipid metabolism (synthesis, not primarily the initial breakdown) occurs in the Smooth Endoplasmic Reticulum (SER) and the cytoplasm.

Other Options:

• Nucleus - Storage of genetic information: Correct. The nucleus houses the cell's main genetic material (DNA) and controls the cell's activities.

• Ribosome - Protein synthesis: Correct. Ribosomes are the cellular machines responsible for translating genetic information into functional proteins.

• Lysosome - Suicidal bags: Correct. Lysosomes contain powerful hydrolytic enzymes that digest waste materials and cellular debris. They are known as "suicidal bags" because if they burst, the enzymes released can digest the cell itself (a process called autolysis).
