What follows is a plain HTML version of the puzzle.
Chapter 9 - Cellular Respiration
Across
2. process that does not require oxygen
4. electron carrier involved in glycolysis
6. a series of proteins in which the high-energy electrons from the Krebs cycle are used to convert ADP into ATP
7. process that releases energy by breaking down glucose and other food molecules in the presence of oxygen
8. first step in releasing the energy of glucose, in which a molecule of glucose is broken into two molecules of pyruvic acid
9. process that requires oxygen
Down
1. process by which cells release energy in the absence of oxygen
3. second stage of cellular respiration, in which pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions
5. amount of energy needed to raise the temperature of 1 gram of water by 1 degree Celsius
