Research Abstract |
We studied the photochemical reaction of photosystems that convert light energy into chemical energy and thylakoid membranes formation as fundamental questions. Photosystem II complexes isolated from a chlorophyll d-dominated cyanobacterium that can utilized near infra-red light for photochemical reaction unlike plantswere analyzed. The results revealed the bioenergetics of photosystems driven by lower energy than those from plants.
