Chlorophyll - Wikipedia

WebWithin the visible light spectrum, chlorophyll absorbs particular wavelengths. The Xanthophyll Cycle is activated when the leaf is exposed to acid. Acidic circumstances promote the development of enzymes that convert zeaxanthin (a yellow xanthophyll) into violaxanthin (an orange xanthophyll) via the intermediate molecule antheraxanthin.
