What is cytochrome c oxidase (CCO)?
Cytochrome c oxidase (CCO) is a vital enzyme in the mitochondrial respiratory chain that drives ATP production.
CCO acts as the final electron acceptor during cellular respiration, directly impacting a cell’s energy output. Red light wavelengths, particularly 650 nm wavelengths, have been shown to stimulate CCO activity, making it central to Photobiomodulation (PBMT) effects.
By enhancing CCO activity in scalp tissues, red light therapy can help increase ATP production in hair follicle cells, improving the cellular environment for hair regrowth and follicle vitality.
