Which organelle is responsible for energy production in the cell?

• A. Mitochondria
• B. Nucleus
• C. Ribosomes
• D. Golgi apparatus

Answer: (A)

Energy production in the cell is carried out primarily by the mitochondria. They convert energy from nutrients into ATP, the cell’s main energy currency, through cellular respiration. glycolysis starts the process in the cytoplasm, but most ATP comes from pyruvate oxidation, the citric acid cycle, and the electron transport chain inside the mitochondria. The inner membrane’s cristae increase surface area to host these reactions, and the mitochondria even contain their own DNA and ribosomes. Other organelles have different roles: the nucleus stores genetic material, ribosomes synthesize proteins, and the Golgi apparatus processes and ships molecules.
