  1. 2. Plant that captures CO2 in mesophyll cell where PEP carboxylase fixes 4-carbon molecule which is transfered to bundle sheath cell where it goes through calvin cycle; captures CO2 in SEPARATE cell from calvin cycle; adapted to hot, dry environments
  2. 5. Following glycolysis in aerobic respiration that results in the combining of free oxygen with protons and electrons from pyruvic acid to make water (Krebs)
  3. 7. Alternate photosynthetic process that prevents photoxidative damage in C3 plants
  4. 10. Breaking down organic molecules to generate ATP
  5. 12. Building complex molecules from simpler ones, requiring energy
  6. 13. Process involving the LOSS of one or more electrons
  7. 14. Capturing light energy and storing energy in organic molecules
  8. 15. Process involving the GAIN of one or more electrons
Down
  1. 1. Light driven splitting of water molecules during photosynthesis
  2. 2. Rubisco helps fix CO2 into organic molecules => ATP and NADPH from the light reactions are used => the cycle produces G3P, which can contribute to sugar and other organic molecule synthesis => the cycle generates RuBP so carbon fixation can continue
  3. 3. Light excites electrons in Photosystems II and I => water is split, supplying electrons and releasing oxygen gas => Electron transport helps establish a proton (H+) gradient => ATP synthase uses that gradient to produce ATP => NADPH carries reducing power to the calvin cycle
  4. 4. Respiration in which the hydrogen is removed from the glucose during glycolysis is typically combined with inorganic ion (in absence of oxygen)
  5. 6. Breaking molecules down, often releasing usable energy
  6. 8. Initial phase of all types of respiration in which glucose is converted to pyruvic acid without involving free oxygen
  7. 9. Captures CO2 at night and stores it in vacuole until daytime when it performs calvin cycle; captures CO2 at a DIFFERENT TIME than calvin cycle is performed; adapted for arid environment
  8. 11. Respiration in which the hydrogen removed form the glucose during glycolysis is transferred by to pyruvic acid, creating substances such as ethyl alcohol or lactic acid
  9. 16. Plant that uses standard calving cycle for carbon fixation, where the first stable molecule produces contains 3 carbon atoms; adapted to cool, wet environments with moderate sunlight
