Across
  1. 1. a type of fermentation where pyruvate is reduced directly by NADH to form lactate as an end product
  2. 9. 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. 10. anaerobes carry out only fermentation or anaerobic respiration and cannot survive in the presence of oxygen
  4. 12. the electron donor in a redox reaction
  5. 15. how animals derive energy from the things we eat; includes aerobic and anaerobic respiration
  6. 16. a type of fermentation where pyruvate is converted to ethanol
  7. 18. a partial degrading of sugars that occurs WITHOUT the use of oxygen
  8. 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
  9. 20. degrades by breaking glucose into two molecules of a compound called pyruvate; occurs in the cytoplasm
Down
  1. 2. the diffusion of ions across a semi-permeable membrane
  2. 3. in the citric acid cycle, this combines with the carbons from acetyl CoA to make a six carbon chain
  3. 4. the enzyme that makes ATP from ADP and inorganic phosphates
  4. 5. 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
  5. 6. the electron acceptor in a redox reaction
  6. 7. during glycolysis, an enzyme adds a second phosphate; this can be allosterically inhibited by ATP
  7. 8. 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
  8. 11. proteins that act as electron characters between ubiquinane and oxygen
  9. 13. a catabolic pathway in which oxygen is consumed as a reactant along with organic fuel
  10. 14. the oxidizing agent in respiration; electron acceptor and carrier
  11. 17. anaerobes can make enough ATP to survive using either fermentation or respiration
