Biology Test 4
| Question | Answer |
|---|---|
| Primary source of energy that almost all organisms use | ATP |
| Make their own food | autotrophs |
| get food from other organisms | heterotrophs |
| happens in ATP to get your energy in your cells | breaking of a phosphate bond |
| reactants of photosynthesis | carbon dioxide and water |
| products of photosynthesis | oxygen and sugars |
| organelle where photosynthesis takes place | chloroplast |
| three stages of photosynthesis | light reaction, calvin cycle, electron transport chain |
| stage of photosynthesis that takes place in the thylakoid | light reaction |
| stage of photosynthesis that takes place in the stoma | calvin cycle |
| stage of photosynthesis that takes place in the thylakoid membrane | electron transport chain |
| pigment that helps plants absorb light to make energy | chlorophyll |
| clusters of pigments embedded in the membrane of disk-shaped structures | thylakoids |
| process where electrons are transported through proteins, which in turn pumps in protons | electron transport chain |
| what ATP-synthase makes | ATP |
| what plants do to keep from loosing water on hot days | close their stoma |
| factors that affect the rate of photosynthesis | light intensity, carbon dioxide levels, and temperature |
| complex process by which cells make ATP by breaking down organic compounds | cellular respiration |
| reactants of cellular respiration | sugars and oxygen |
| products of cellular respiration | carbon dioxide, water, and ATP |
