Chlorophyll picks up electrons from
WebH2O Electrons are stripped from water in the light reactions of photosynthesis. This is one of the reasons plants need water. This is one of the reasons plants need water. What provides the carbon atoms that are incorporated into sugar molecules in the Calvin cycle? WebThe high energy electrons come from chlorophyll molecules that have absorbed sunlight. Where do the high-energy electrons carried by NADPH come from? The Calvin cycle uses carbon dioxide molecules as well as ATP and NADPH from the light-dependent reactions to make sugars. What does the Calvin Cycle use to produce high-energy sugar?

WebJul 3, 2011 · When chlorophyll or accessory pigments absorb photons it causes the electrons from chlorophyll A to be picked up by an acceptor molecule and sent … WebOnce an electron has gone down the first leg of the electron transport chain, it arrives at PSI, where it joins the chlorophyll a special pair called P700. Because electrons have lost energy prior to their arrival at PSI, they must be re-energized through absorption of …
Web1. light excites electrons in chlorophyll in photosystem II 2.electrons are transferred to primary electron acceptor 3. water is split and P680 (special chlorophyll) grabs the electrons=O2 releases 4. an electron transport chain transfers electrons to PSI, pumping protons into the thylakoid space WebA. comes from food molecules B. electrons have high potential energy in the bonds in organic molecules. C. electrons flow from water to reaction center chlorophyll in photosystem II to chlorophyll in photo I to NADPH, reducing to NADPH. D. energy is released by redox reactions in electron transport is used to trans H+ across membrane.
WebA complex of proteins associated with a special pair of chlorophyll a molecules and a primary electron acceptor. Located centrally in a photosystem, this complex triggers the light reactions of photosynthesis. WebThe energy given to the electron then travels from one pigment molecule to another until it reaches a pair of chlorophyll a molecules called the reaction center. This energy then excites an electron in the reaction center causing it to break free and be passed to the primary electron acceptor.
