The correct answer is a mitochondrial theory of aging. Â
The mitochondrial theory of aging, an alternative of the free radical theory of aging, suggests that congregation of destruction to mitochondria and mitochondrial DNA result in aging of animals and humans. In such instances, there seems to be a significant oxidative destruction of the cells. Â
This destruction results in the generation of decay in tiny cellular bodies, which offer energy that is required for cell growth, function, and repair. Â
