High light absorption
WebLight absorption in PSI. The electron arrives at photosystem I and joins the P700 special pair of chlorophylls in the reaction center. When light energy is absorbed by pigments and passed inward to the reaction center, the electron in P700 is boosted to a very high energy level and transferred to an acceptor molecule. WebSo we see that beta carotene absorbs light with wavelengths of approximately 450 to 500 nanometers for a range and it absorbs strongly in the visible region. To explain why beta carotene is orange, we need to look at a little bit more detail at the visible region of the electromagnetic spectrum, and so here we have the different colors.
