Term | Definition |
---|---|
Calorie (Uppercase) | Measure of heat energy in food; equivalent to 1000 calories |
Cellular Respiration | Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen. |
Aerobic | Process of that requires oxygen. |
Anaerobic | Process that does not require oxygen. |
Glycolysis | First set of reactions in cellular respiration in which a molecule of glucose is broken into two molecules of pyruvic acid. |
NAD+ | Electron carrier involved in glycolysis. |
Krebs Cycle | Second stage of cellular respiration in which pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions. |
Matrix | Innermost compartment of the mitochondrion. |
Fermentation | Process by which cells release energy in the absence of oxygen. |
calorie (lowercase) | amount of energy needed to raise the temperature of water 1 degree Celsius. |
Electron Transport Chain | Series of electron carrier proteins that shuttle high-energy electrons during ATP-generating reactions. |
