1. aerobic - process that requires oxygen.
2. anaerobic - process that does not require oxygen.
3. calorie - amount of energy needed to raise the temperature of 1 gram of water by 1 degree Celsius.
4. cellular respiration - process that releases energy by breaking down glucose and other food molecules in the presence of oxygen.
5. electron transport chain - a series of proteins in which the high-energy electrons from the Krebs cycle are used to convert ADP into ATP.
6. fermentation - process by which cells release energy in the absence of oxygen.
7. glycolysis - first step in releasing the energy of glucose, in which a molecule of glucose is broken into two molecules of pyruvic acid.
8. Krebs cycle - second stage of cellular respiration, in which pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions.
9. NAD+ - (nicotinamide adenine dinucleotide) - electron carrier involved in glycolysis.
