cellular respiration

1. A substance made from sugars in milk, by the action of certain enzymes
3. process by which cells release energy in the absence of oxygen
5. plays a central role in sugar metabolism
7. an organic molecule that binds to the active sites of certain enzymes to assist in the catalysis of a reaction
9. process that requires oxygen
11. the process by which plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water
12. process that does not require oxygen
14. intermost compartment of the mitochondria
15. first set of reactions in cellular respiration during which a molecule of glucose is broken into 2 molecules of pyruvic acid
16. acts as an energy carrier, transferring electrons from one reaction to another

2. amount of energy needed to raise the temperature 1 gram of water 1 degree Celsius
4. Universal electron carrier
6. process that releases energy by breaking down glucose and other food molecules in the presence of oxygen
8. an incidental or secondary product made in the manufacture or synthesis of something else
10. second stage of cellular respiration in which pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions
13. electron carrier involved in glycolysis
