  1. 4. relating to any organism or process that does not require oxygen
  2. 6. long, tube-like organ that forms part of the complex network of vessels that run through the body and transport blood to all the body’s cells
  3. 7. type of cellular respiration that does not require oxygen
  4. 9. an individual living thing
  5. 10. relating to any organism or process that requires oxygen
  6. 11. 3-carbon product of glycolysis; also known as pyruvic acid
  7. 12. fluid connective tissue that circulates throughout the body through blood vessels
  8. 13. second stage of cellular respiration in which two pyruvate molecules from the first stage react to form ATP, NADH, and FADH2 in the presence of oxygen
  9. 15. multicellular, heterotrophic eukaryote with specialized cells that lack cell walls; member of the animal kingdom
  10. 18. third stage of cellular respiration, which occurs on the inner membrane of mitochondria, requires oxygen, and produces up to 34 molecules of ATP

Down
  1. 1. first stage of cellular respiration in which glucose is split in the absence of oxygen to form two molecules of pyruvate and a net total of two ATP
  2. 2. a biochemical process in which cells break down glucose and oxygen to make carbon dioxide, water, and ATP for energy
  3. 3. top layer of Earth's surface containing weathered rocks, minerals, and organic material
  4. 5. type of anaerobic respiration that includes glycolysis followed by the conversion of pyruvic acid to one or more other compounds and the formation of NAD+
