| A | B |
| glucose | sugar produced by plants during photosynthesis |
| chlorophyll | pigment in leaves that traps sunlight; reflects green color |
| oxygen | gas produced by plants during photosynthesis |
| glycolysis | process in which glucose is split into two pyruvate molecules; 2 ATP are produced. |
| Krebs Cycle | series of chemical reactions that produces 2 ATP and 4 CO2 |
| electron transport chain | process that produces 34 ATP molecules and 6 H2O. |
| mitochondria | the powerhouse of the cell; citric acid cycle and electron transport chain occur here |
| cytoplasm | this is where glycolysis occurs |
| fermentation | alternative to cellular respiration; anaerobic |
| lactic acid | builds up in oxygen-deprived muscle cells |
| alcohol | byproduct of alcoholic fermentation |
| pyruvate | this molecule is formed after glucose is split |
| photosynthesis | process in which plants produce sugar |
| cellular respiration | process in which energy from food is used to make ATP; aerobic |
| anaerobic | without oxygen |
| adenosine triphosphate | "cell fuel" |
| heterotroph | an organism that must consume other organisms for food |
| carbon dioxide | waste produced released when we exhale |
| light reactions | occurs in the thylakoids; light energy is converted to chemical energy. |
| thylakoid | folded membrane in chloroplast; where light reactions occur. |
| ATP Synthase | enzyme complex located in the inner mitochondrial membrane; used to make ATP |
| stroma | liquid inside of chloroplast |
| stomata | openings on leaves for gas exchange |
| acetyl CoA | a product of the transition reaction that is needed in order to begin the Krebs cycle |
| Calvin Cycle | series of chemical reactions that occur in the stroma; results in the production of glucose |
| autotroph | organism capable of making its own food |
| yeast | a unicellular fungi that is used to make bread, alcoholic beverages |
| oxygen | the final electron acceptor in the electron transport chain |
| chemiosmosis | the movement of H+ ions from high concentration to low concentration; allows for the production of ATP |
