The inner membrane bears oxysomes. Oxysomes take part in ATP synthesis through oxidative phosphorylation. The oxysomes are also called F0​ - F1​ particles. They are made up of F0​ base, Stalk and F1​ head. The F0​ part function as proton tunnels. Stalk part of elementary particle has coupling factor while heads have ATP as for ATP synthesis.

1. ATP synthesis: Oxysomes are responsible for the production of ATP (adenosine triphosphate), which is the main energy currency of the cell. They contain the enzyme ATP synthase, which synthesizes ATP using the energy released during the electron transport chain.

2. Electron transport chain: Oxysomes play a crucial role in the electron transport chain, which is a series of protein complexes located in the inner mitochondrial membrane. This chain is responsible for transferring electrons from NADH and FADH2 to oxygen, generating a proton gradient across the membrane that is used to produce ATP.

3. Oxidative phosphorylation: Oxysomes are involved in oxidative phosphorylation, which is the process by which ATP is synthesized using the energy released during electron transport. They facilitate the coupling of the electron transport chain with ATP synthesis by allowing the protons to flow back into the mitochondrial matrix through ATP synthase.

4. Cellular respiration: Oxysomes are essential for cellular respiration, which is the process by which cells generate energy from glucose or other organic molecules. They enable the efficient production of ATP by coordinating the electron transport chain and oxidative phosphorylation.

Overall, oxysomes are critical components of mitochondria that are directly involved in ATP production and energy metabolism in cells.
