| Question | Answer |
|---|---|
| glycolysis | a biochemical pathway in which one six-carbon molecule of glucose is oxidized to produce two three-carbon molecules of pyruvic acid |
| fermentation | the combination of glycolysis and these additional pathways, which regenerate NAD+ |
| lactic acid fermentation | an enzyme converts pyruvic acid made during glycolysis into another three-carbon compound |
| alcoholic fermentation | to convert pyruvic acid into ethyl alcohol |
| kilocalories | energy is measured in this unit |
| Ethyl Alcohol | glucose-->glycolysis-->pyruvic acid-->co2-->2-carbon compound-->? |
| Lactic Acid | glucose-->glycolysis-->pyruvic acid-->? |
| Lactic Acid products | cheese, buttermilk, yogurt, sour cream, etc. |
| Alcoholic products | bread, alchoholic beverages, sparkling wines, chaampagne, etc. |
| Glycolysis | Glucose-->6-carbon compound-->2 molecules of G3P-->2 molecules of new 3-carbon compound-->2 molecules of pyruvic acid |
| Cellular respiration formula | Organic compounds-->glycolysis-->pyruvic acid + ATP-->aerobic respiration-->co2 + h20--> or + ATP |
| fermentation formula | Organic compound-->glycolysis-->pyruvic acid + ATP-->anaerobic pathways--> lactic acid, ethyl alcohol, or other compounds |
| Glycolysis products | small amount of atp and nadh |
| aerobic respiration | if oxygen is present in the cell's environment, pyruvic acid is broken down and NADH is used to make a large amount of ATP |
| Cellular respiration | the complex process in which cells make adenosine triphosphate by breaking down organic compounds |
