Frontiers in Photobiology 4:1817712 (10 pages) DOI 10.3389/fphbi.2026.1817712; here, authors warmly wished, in their Acknowledgements section, Govindjee's 94th birthday: "Fiat lux!" (i.e., Let There Be Light). Further, an original open-source figure of the Z-Scheme of photosynthesis and the location of elements therein is beautifully provided for education and lectures in this paper!
