Photosynthesis is based on a fascinating interplay between proteins, pigments and membranes. The cleavage of water molecules takes place in photosystem II which is excited by light. Recent structure elucidation of photosystem II helped in understanding the electron transfer reaction but the water splitting mechanism is still not solved. The light energy is stored in ATP, which is synthesized by the ATP Synthase, a molecular motor. Its membrane part, the c‐ring, mediates the transfer of protons. Structure and function of ATP Synthase are currently under intensive investigation.
