1. What Is The Powerhouse Of The Cell?
The powerhouse of the cell is the mitochondrion. Mitochondria are organelles found in eukaryotic cells that produce adenosine triphosphate (ATP), the main energy currency of the cell. They are essential for cellular respiration and overall cell function.
Mitochondria are often called the “powerhouses” of the cell because they generate most of the cell’s supply of ATP, used as a source of chemical energy. This process involves a series of chemical reactions known as cellular respiration. The inner mitochondrial membrane is folded into cristae, which increase the surface area for these reactions to occur. Furthermore, understanding mitochondrial function and cellular energy production is critical in fields ranging from basic biology to medical research. Have more questions?
