7. A process of energy conversion that releases energy from food in the presence of oxygen
9. Process that requires oxygen
10. An electron carrier involved in cellular respiration
11. A second stage of cellular respiration, in which pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions

1. Cell organelle that converts the chemical energy stored in food into compounds for the cell to use
2. The innermost compartment of the mitochondria and the site of the Krebs cycle reactions
4. An enzyme for the synthesis of ATP; it consists of a cluster of proteins that spans the cell membrane and allows hydrogen ions (H+) to pass
5. A process by which cells release energy in the absence of oxygen
6. The amount of energy needed to raise the temperature of 1 gram of water 1 degree Celsius
