Mitochondria

Definition

Mitochondria are small structures in cells that produce energy for the body, often referred to as the powerhouses of the cell.

Scientific / Technical Definition

Mitochondria are membrane-bound organelles found in the cytoplasm of eukaryotic cells. They are responsible for generating the majority of the cell's supply of adenosine triphosphate (ATP) through the process of oxidative phosphorylation while also playing roles in regulating cellular metabolism.

Benefits

• Provide energy to cells by generating ATP.
• Help regulate cellular metabolism.
• Play a role in the process of cell signaling, cellular differentiation, and cell death.
• Assist in maintaining control of the cell cycle and cell growth.

Examples

• While mitochondria are not found in food sources, cells in energy-dense organs like muscles and the brain have a high concentration of mitochondria.

Additional Information

• Importance: Mitochondria are crucial for energy production, cellular metabolism, and overall cell health. Dysfunctional mitochondria can lead to metabolic disorders and diseases.
