What is known as the powerhouse of the cell?

The mitochondria are referred to as the powerhouse of the cell because they are the organelles responsible for producing adenosine triphosphate (ATP), which is the main energy carrier in cells. This process, known as cellular respiration, involves converting the energy stored in food molecules into a usable form for the cell.

Mitochondria have a unique structure, with a double membrane that allows for the creation of a proton gradient, which is essential for ATP production. Their role is crucial for the energetic demands of cells, as nearly all cellular functions require energy in the form of ATP. This is why mitochondria are often highlighted as fundamental to cellular energy production and overall cell function.
