Unformatted text preview: electron transport system, are used to replace the electrons lost by photosystem I that were used to form NADPH. • Water’s electrons are passed to photosystem II. The water's H + is used in the H + gradient (and can be passed to NADP + ) and its oxygen is released as oxygen gas molecules. To summarize, the low energy electrons from water are elevated in energy by passing through both photosystem II and photosystem I on the path to being trapped by NADP + where their potential energy will be used for the high energy reduction of carbon in the Calvin cycle. Along the way, ATP, needed for the endergonic Calvin cycle, is also produced. Organization of the Light Reaction Components in the Thylakoid...
