-these enzymes include catalase, D-amino
acid oxidase, uric acid oxidase.
- these enzymes require oxygen (oxidative)
Breaks down long chains of fatty acids using oxidation
Creates hydrogen peroxide to oxidate toxins turning them in to water and oxygen
Breaking down of fatty acid creates metabolic energy
Prevents chemicals such as oxalate and fatty acid chains from building up
As time passes, the nucleus can let unwanted debris inside causing problems with the cell
The proteins that form the nuclear pores which allow certain things in and out of the cell do not get repaired or replaced over time
As time passes, the nuclear pores can allow unwanted or dangerous objects into the nucleus and can cause damage to the cell’s DNA.
