Across
  1. 1. acid cycle also referred to as the Krebs Cycle
  2. 4. transport the process in which electrons are handed down by NADH and FADH2 to carrier molecules which actively pumps H+ ions into the inner mitochondrial membrane. the electrons are passed along the chain until they reach oxygen to form water.
  3. 8. to break/cut with water. (opposite of dehydration synthesis)
  4. 10. phosphorylation the process in which electrons are oxidized so they can be reused for glycolysis, PDC, and Krebs. (related to electron transport)
  5. 12. electron acceptor what part oxygen plays in oxidative phosphorylation (electron transport chain). last molecule in the electron transport chain to accept electrons.
  6. 13. half a glucose molecule
  7. 15. mitochondrial membrane where electron transport takes place
  8. 16. regeneration of empty electron carriers in the absence of oxygen. (anaerobic respiration) produces lactic acid and only 2 net ATP are made
  9. 18. Cycle the step of cellular respiration in which oxaloacetic acid is combined with Acetyl Co-A to form citric acid. Citric acid is broken down, one carbon at a time and arranged to for the original oxaloacetic acid molecule. 3 molecules of NADH, one molecule of FADH2, and one molecule of ATP are made and CO2 is released.
Down
  1. 2. what an electron carrier becomes when it accepts a pair of electrons.
  2. 3. A attaches to the 2-carbon structure that was prepared to enter the Krebs Cycle
  3. 5. when one molecule of glucose it split in half. literally means "sugar splitting"
  4. 6. what an electron carrier becomes when it gives up its pair of electrons
  5. 7. triphosphate (ATP)
  6. 9. bonded to three phosphate molecules. a lot of energy is stored in the bond that holds the 3rd phosphate to the molecule
  7. 11. without oxygen
  8. 14. synthase allows the H+ ions back into the matrix and harnesses the energy to phosphorylate ADP
  9. 17. requiring oxygen
