A mitochondria model is a physical representation of the structure and function of the mitochondria, which are organelles found in most eukaryotic cells that are responsible for producing energy for the cell. These models are typically used in educational or scientific settings, such as biology or biochemistry classes.

The model is usually made of synthetic materials, such as plastic or foam, and may be life-sized or scaled down in size. It typically includes the major structures of a mitochondrion, such as the outer and inner membranes, cristae, and matrix. Some models may also include a representation of the electron transport chain and ATP synthase, which are the main components responsible for energy production in the mitochondria.

Mitochondria models can be used to demonstrate the relationship between the different structures in the mitochondria and their roles in energy production, as well as the process of oxidative phosphorylation. They may also be used to teach about the effects of mitochondrial dysfunction, which can lead to various diseases and disorders, such as mitochondrial myopathies or neurodegenerative disorders. Some models may also include a cross-section or cutaway view to show the internal structure of the mitochondrion in greater detail.
