What is the main function of the mitochondrion in the cell?

Explanation:
The main concept here is that mitochondria are the cell’s energy producers. They generate ATP through cellular respiration, using the citric acid cycle and the electron transport chain in the inner mitochondrial membrane. Nutrients are processed to yield NADH and FADH2, which feed electrons through the chain. The resulting proton gradient powers ATP synthase to convert ADP and phosphate into ATP, the energy currency the cell uses for most activities. Other organelles handle different jobs: ribosomes synthesize proteins, the Golgi apparatus packages and sorts them, and lysosomes are involved in digestion and are formed within the endomembrane system. So the mitochondrion’s primary function is producing ATP via cellular respiration.
