Across
  1. 3. a compound that donates one hydrogen and two electrons to another molecule, to reform NADP+; is an electron donor.
  2. 4. a chemical reaction in which a compound is broken down by light; in photosynthesis, water molecules are split by this.
  3. 7. a reaction in which an atom or molecule loses electrons.
  4. 8. the process of incorporating CO2 into carbohydrate molecules.
  5. 11. transport chain /a series of progressively stronger electron acceptors; each time an electron is transferred, energy is released.
  6. 13. the photosynthetic membrane withing a chloroplast that contains light-gathering pigment molecules and electron transport chain.
  7. 15. the first set of photosynthesis in which light energy excites electrons in chlorophyll molecules, powers chemiosmotic ATP synthesis, and results in the reduction of NADP+ to NADPH.
  8. 16. a cyclic set of reactions occurring in the stroma of chloroplasts that fixes the carbon of CO2 into carbohydrate molecules and recycles coenzymes.
  9. 17. the fluid-filled space inside a thylakoid.
  10. 19. a reaction in which an atom or molecule gains electrons.
  11. 20. stacks of thylakoids.
Down
  1. 1. a system of interconnected flattened membrane sacs forming a separate compartment withing the stroma of a chloroplast.
  2. 2. a molecule containing two high-energy phosphate bonds that may be formed by breaking one of the phosphate bonds in ATP.
  3. 5. the second set of reactions in photosynthesis (the Calvin cycle); these reactions do not require solar energy.
  4. 6. a packet of light
  5. 8. a membrane-bound organelle in green plant and algal cells that carries out photosynthesis.
  6. 9. a compound that accepts one hydrogen atom and two electrons, forming NADPH; is an electron acceptor.
  7. 10. a molecule containing three high-energy phosphate bonds that acts as the primary energy-transferring molecule in living organisms.
  8. 12. the light-absorbing green-coloured pigment that begins the process of photosynthesis.
  9. 14. a cluster of photosynthetic pigments embedded in a thylakoid membrane of a chloroplast that absorbs light energy.
  10. 18. groups of unstacked thylakoids between grana.
