Where is laser therapy administered and treated?
Laser therapy uses an intense, narrow beam of light to remove or destroy cancer and abnormal cells that can turn into cancer. Tumor cells absorb light of different wavelengths (or colors) than normal cells do. So, tumor cells can be targeted by selecting the proper wavelength of the laser. Laser therapy is a type of local treatment, which means it treats a specific part of your body.

What is the effect of light on the electron transport chain?
As light is absorbed by Cytochrome C oxidase (COX), it stimulates the electron transport chain to increase the production of adenosine triphosphate (ATP) within the mitochondria. When tissue is damaged, the production of ATP in the cell is impaired which slows down the metabolism of the cell as a protective mechanism.
