- 6. the second stage of cellular respiration in which pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions.
- 9. the process that releases energy from food in the presence of oxygen.
Down
- 1. a process that requires oxygen.
- 2. the innermost compartment of the mitochondrion.
- 3. a process that does not require oxygen.
- 4. the first set of reactions in cellular respiration during which 1 molecule of glucose, a 6-carbon compound, is transformed into 2 molecules of pyruvic acid, a 3-carbon compound.
- 5. the process by which cells release energy in the absence of oxygen.
