| Term | Definition |
|---|---|
| cellular respiration | the process by which cells produce energy from carbohydrates; atmospheric oxygen combines with glucose to form water and carbon dioxide |
| pyruvic acid | the three-carbon compound that is produced during glycolysis and needed for both the aerobic and anaerobic pathways of cellular respiration that follow glycolysis |
| NADH | an electron carrier molecule |
| anaerobic | describes a process that does not require oxygen |
| aerobic respiration | a process where, if oxygen is present in the cell's environment, pyruvic acid is broken down and NADH is used to make large amounts of ATP |
| glycolysis | the anaerobic breakdown of glucose pyruvic acid, which makes a small amount of energy available to cells in the form of ATP |
| NAD+ | nicotinamide adenine dinucleotide, an organic molecule that serves as an electron carrier by being oxidized to NAD+ and reduced to NADH |
| fermentation | the breakdown of carbohydrates by enzymes, bacteria, yeasts, or mold in the absence of oxygen |
| lactic acid fermentation | the chemical breakdown of carbohydrates that produces lactic acid as the main end product |
| alcoholic fermentation | the anaerobic process by which yeasts and other microorganisms break down sugars to form carbon dioxide and ethanol |
