The mitochondria are double-membrane organelles found in the cytoplasm of eukaryotic cells. The outer membrane is smooth while the inner membrane is highly folded into structures called cristae. The space between the two membranes is known as the intermembrane space, while the space enclosed by the inner membrane is called the matrix.
The main function of mitochondria is to produce energy in the form of adenosine triphosphate (ATP) through a process called cellular respiration. This process involves the breakdown of glucose and other organic molecules in the presence of oxygen to generate ATP. The enzymes and proteins involved in this process are located in the inner membrane and matrix of the mitochondria.
In addition to energy production, mitochondria also play a role in regulating cell metabolism, calcium signaling, and apoptosis (programmed cell death). They are also involved in the synthesis of certain molecules and the regulation of cellular processes.
Overall, mitochondria are essential organelles for the survival and functioning of eukaryotic cells, as they provide the energy needed for various cellular activities.

Mitochondria: Structure and Function
Structure:
- Double-membrane-bound organelles found in eukaryotic cells
- Outer membrane: Smooth and permeable to small molecules
- Inner membrane: Highly folded into cristae, increasing surface area
- Matrix: Fluid-filled space containing enzymes, DNA, and ribosomes
Function:
- Cellular Respiration:
- Site of oxidative phosphorylation, where energy is extracted from glucose and stored as ATP
- Electron transport chain, located in the inner membrane, generates a proton gradient used to drive ATP synthesis
- Energy Production (ATP):
- Primary energy source for most eukaryotic cells
- ATP produced through glycolysis, citric acid cycle, and oxidative phosphorylation
- Metabolism:
- Involved in fatty acid oxidation, amino acid metabolism, and heme synthesis
- Calcium Homeostasis:
- Regulate calcium levels within the cell
- Apoptosis (Programmed Cell Death):
- Release cytochrome c from the matrix, triggering cell death
- Other Functions:
- Synthesis of heme, coenzymes, and phospholipids
- Regulation of reactive oxygen species (ROS) production
