Function of Mitochondria

Cellular biology is a fundamental aspect of understanding living organisms. One critical component of cells is the organelles, which perform various functions necessary for cellular operation. Among these organelles, mitochondria play a vital role in energy production. They are often referred to as the "powerhouses" of the cell.

Mitochondria are responsible for generating adenosine triphosphate (ATP), which is the primary energy carrier in cells. The process of ATP production occurs through cellular respiration, which includes glycolysis, the citric acid cycle, and oxidative phosphorylation. Understanding how mitochondria function is crucial for studying cellular energy metabolism and overall cellular health.
