  6. What are the photons that our eyes can see called?
    visible light
  7. What is the full range of photon energies called?
    electromagnetic spectrum
  8. What are molecules that absorb light energy called?
  9. What is the pigment within human eyes called?
  10. While chlorophyll is the primary pigment involved in photosynthesis, plants contain what other pigments?
    accessory pigments
  11. What are a group of pigments that capture violet to blue-green light, some wavelengths not efficiently absorbed by chlorophyll?
  12. The excitation energy is funneled to what key chlorophyll a molecule?
    reaction center
  13. The excited electron is then shuttled along what series of electron-carrier molecules embedded in the membrane?
    electron transport system
  14. What is the cellular process responsible for almost all of the adenosine triphosphate harvested from food and for all the ATP produced by photosynthesis called?
  15. The two-stage process that plants use to produce ATP and NADPH is known as what?
    noncyclic photophosphorlation
  16. What is the portion of the photosystem that contains all the pigment molecules called?
    antenna complex
  17. Protons diffuse back out of the thylakoid space toward lower concentration through what channel proteins?
    ATP synthases
  18. What is the most abundant protein in chloroplasts and is thought to be the most abundant protein on earth?
    rubisco (RuBP carboxylase)
  19. What are the leaf openings of plants called?
  20. What is a process in which carbon dioxide is released without the production of ATP or NADPH called?
  21. Some plants are able to adapt to climates with higher temperatures by performing what? In this process, these plants are able to fix carbon using different types of cells and chemical reactions within their leaves and thereby avoiding a reduction in photosynthesis due to higher temperatures.
    C4 photosynthesis

    priming reactions
  30. What is the second stage of glycolysis called?
    cleavage reactions
  31. What is the third stage of glycolysis called?
    energy-harvesting reactions
  32. What is a catabolic process in which the final electron acceptor is an organic molecule called?
  33. The acetyl group removed from pyruvate combines with a cofactor called coenzyme A, which forms what compound?
  34. What is a collective term describing the series of membrane-associated electron carriers embedded in the inner mitochondrial membrane called?
    electron transport chain
  35. What is the internal compartment of a mitochondrion that contains the enzymes that carry out the reactions of the Krebs cycle called?
  36. What is the outer compartment sometimes called?
    intermembrane space
