Mitochondria are often referred to as the powerhouses of the cell because they generate adenosine triphosphate (ATP), which is the primary energy carrier in all living organisms. The process of cellular respiration occurs in mitochondria, where glucose and other substrates are oxidized to produce ATP. This process involves a series of biochemical reactions, including the Krebs cycle and oxidative phosphorylation, which ultimately result in the conversion of energy stored in glucose into ATP.

The other options listed do not directly correlate with mitochondrial functions. Glucose is a product of photosynthesis that occurs in plants, not in mitochondria. Chlorophyll is a pigment found in plants that is essential for photosynthesis, while DNA is the molecule that carries genetic information and is primarily found in the nucleus of the cell and not produced by mitochondria. Therefore, the correct answer highlights the critical role of mitochondria in energy production through ATP synthesis.
