Unit 3 Vocabulary
Science vocabulary for cellular respiration and photosynthesis.
| Term | Definition |
|---|---|
| Producers | Organisms that produce their own food |
| Photosynthesis | Plants use the sun's energy to convert water and carbon dioxide into sugars |
| Photosynthesis equation | 6CO2 + 6H2O ------> C6H12O6 + 6O2 |
| Chloroplast | An organelle found in plant cells where photosynthesis occurs |
| Thylakoids | A flattened membrane sac inside the chloroplast |
| NADPH and ATP | molecules that carry energy from the light dependent reaction to the light-independent reaction |
| Carbon dioxide | molecule that is added to the light independent reaction in photosynthesis |
| Water | Molecule that enters into the light dependent reaction and is broken by sunlight energy in photosynthesis |
| Oxygen | Molecule that is released from the light dependent reaction as a waste in photosynthesis |
| Sugar | Product of the light independent reaction |
| Cellular Respiration | Process that releases energy from sugar in the presence of oxygen |
| Anaerobic respiration | Respiration that does not require oxygen |
| Mitochondria | Organelle that is the site of cellular respiration |
| Glycolysis | The process that breaks down glucose into 2 pyruvate molecules |
| Krebs Cycle | Process where the energy from pyruvate is converted into NADH and FADH2; produces carbon dioxide as a waste |
| NADH and FADH2 | Molecules that carry energy from the krebs cycle to the electron transport chain |
| Electron transport chain | Process that takes the energy from NADH and FADH2 and turns it into ATP |
| Anaerobic Process | Glycolysis and fermentation |
| Pyruvate | The molecule that enters the krebs cycle |
| Carbon dioxide | Molecule that is produced as a waste in the kreb cycle in cellular respiration |
| Water | molecule that is created as a product of the electron transport chain in cellular respiration |
| Carbon dioxide in cellular respiration | molecule that is produced as a waste product in cellular respiration |
