What is the function of the mitochondria in eukaryotic cells?

Mitochondria are organelles found in eukaryotic cells that play a crucial role in energy production. They are often referred to as the powerhouse of the cell because they generate most of the energy that cells need to function properly.
The primary function of mitochondria is to produce ATP (adenosine triphosphate) through a process called cellular respiration. ATP is the energy currency of the cell, and it is required for a wide range of cellular processes such as protein synthesis, muscle contraction, and nerve impulse transmission.
