Across
  1. 2. In eukaryotic cells, electron carriers are arranged in the membrane in a way that H+ is accepted in the mitochondrial matrix and deposited in the intermembrane space. The H+ gradient that results is called this
  2. 3. 90% of the energy released previously is stored in the mitochondrion to make ATP; this stage of cellular respiration is powered by redox reactions; occurs in the mitochondrial membrane
  3. 5. the electron acceptor in a redox reaction
  4. 8. a type of fermentation where pyruvate is converted to ethanol
  5. 12. enters the citric acid cycle first carrying carbons; upon entering the mitochondria via active transport, pyruvate is first converted into this; a coenzyme that is used to make citrate
  6. 13. the oxidizing agent in respiration; electron acceptor and carrier
  7. 14. how animals derive energy from the things we eat; includes aerobic and anaerobic respiration
  8. 16. a catabolic pathway in which oxygen is consumed as a reactant along with organic fuel
  9. 17. anaerobes carry out only fermentation or anaerobic respiration and cannot survive in the presence of oxygen
  10. 18. a partial degrading of sugars that occurs WITHOUT the use of oxygen
  11. 20. proteins that act as electron characters between ubiquinane and oxygen
Down
  1. 1. during glycolysis, an enzyme adds a second phosphate; this can be allosterically inhibited by ATP
  2. 4. the enzyme that makes ATP from ADP and inorganic phosphates
  3. 6. the electron donor in a redox reaction
  4. 7. the diffusion of ions across a semi-permeable membrane
  5. 9. anaerobes can make enough ATP to survive using either fermentation or respiration
  6. 10. in the citric acid cycle, this combines with the carbons from acetyl CoA to make a six carbon chain
  7. 11. degrades by breaking glucose into two molecules of a compound called pyruvate; occurs in the cytoplasm
  8. 15. a type of fermentation where pyruvate is reduced directly by NADH to form lactate as an end product
  9. 19. breaks the fall of electrons to oxygen in energy releasing reactions; produces lots of ATP; carries electrons; embedded in the inner membrane of the mitochondria
