Across
  1. 4. the process by which cells use oxygen to produce energy from food
  2. 5. a type of protein that speeds up a chemical reaction (catalyst) in a living thing
  3. 7. respiration that requires oxygen, occurs in mitochondria
  4. 9. respiration that does not require oxygen, produces lactic acid
  5. 10. three-carbon compound that forms as an end product of glycolysis
  6. 11. a type of anaerobic respiration in which glucose is broken down into lactic acid
Down
  1. 1. first step of cellular respiration - releasing the energy of glucose, in which a molecule of glucose is broken into two molecules of pyruvic acid
  2. 2. molecules that contain carbon atoms
  3. 3. second stage of cellular respiration, in which pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions
  4. 6. process by which cells release energy in the absence of oxygen
  5. 7. a type of anaerobic respiration in which yeast breaks down sugars and releases ethanol as a byproduct
  6. 8. powerhouse of the cell, organelle that is the site of ATP production
