Question

How are mitochondria connected to the aging process?

Answer 1

Mitochondria:

1. In most eukaryotic species, a mitochondrion is a double-membrane-bound organelle.
2. Mitochondria produce the majority of the cell's adenosine triphosphate through aerobic respiration, which is used as a source of chemical energy throughout the cell.

Connection between mitochondria and aging process:

1. Ageing is associated with a decrease in mitochondrial enzyme function and respiratory chain malfunction.
2. It is linked to a rise in reactive oxygen species and oxidative stress, which contribute to the natural aging process.
3. Improper mitochondrial fission and fusion control, as well as mutations in mitochondrial DNA, are linked to a variety of age-related and neurodegenerative disorders.
