Right light therapy is said to target cytochrome C oxidase, complex IV, of the mitochondria. Most complexes of the mitochondria contain functional groups that absorb one wavelength of visible light or another. Absorption of light may translate into increased membrane potential, which translates into more ATP. This post introduces the role of ATP in…

What happens when to a molecule when it absorbs visible light? A 1999 Scientific American post explored the question of why a brick wall heats up when it absorbs light. Two explanations were given to this seemingly simple lay question: What happens when light strikes an object? Possibility #4 is particularly intriguing because the rate of…
