Photosynthesis and Cellular Respiration
| Question | Answer |
|---|---|
| This molecule is made-up of adenine, ribose, and 3 phosphate groups. | ATP |
| This molecule is made-up of adenine, ribose, and 2 phosphate groups. | ADP |
| Adding a phosphate group to ADP to make ATP _________ energy. | stores |
| Removing a phosphate group from ATP to make ADP _________ energy. | releases |
| Organisms that produce their own food are called | Autotrophs or producers |
| Organisms that have to consume food for energy are called | Heterotrophs or consumers |
| Found in plants, this pigment reflects green light. | Chlorophyll |
| Molecules that absorb the sun's energy are called | pigments |
| 1st step of cellular respiration - breaks down glucose into pyruvic acid. | Glycolysis |
| What are the reactants of cellular respiration? | oxygen and glucose |
| What are the reactants of photosynthesis? | carbon dioxide and water |
| What are the products of cellular respiration? | carbon dioxide and water |
| What are the products of photosynthesis? | oxygen and glucose |
| 2nd step of cellular respiration - breaks down pyruvic acid into carbon dioxide. | Kreb's Cycle |
| 3rd step of cellular respiration - produces water and up to 34 molecules of ATP. | Electron Transport Chain |
| Photosynthesis takes place in the | chloroplast |
| Cellular respiration takes place in | mitochondria |
| What lab technique did we use to separate the different pigments of a spinach leaf? | paper chromatography |
| 1st step of photosynthesis - requires light energy to split water into oxygen gas and hydrogen atoms. | Light-Dependent Reaction |
| 2nd step of photosynthesis - uses ATP as its source of energy to add hydrogen atoms to carbon dioxide and make glucose. | Calvin Cycle |
| The initial source of energy for most communities is | sunlight. |
| The energy released from ATP breaking down into ADP is used to perform | cellular work & life functions. |
| Special protein used in Electron Transport Chain that spins as hydrogen ions move through it. The spinning motion provides energy to make ATP molecules. | ATP Synthase |
| Amount of energy that can be passed on from one trophic level to the next. | 10% |
| Organisms that break down organic matter and return nutrients to the environment. | decomposers |
| Organisms that feed on (consume) dead or decaying matter. | detritivores |
| Anaerobic process that harvests energy from food to make ATP. | fermentation |
| Type of fermentation that produces lactic acid. | lactic acid fermentation |
| Type of fermentation that produces ethyl alcohol and carbon dioxide. | alcoholic fermentation |
| Type of organism that requires oxygen to survive. | obligate aerobe |
| Type of organism that requires an oxygen-free environment to survive (is poisoned by oxygen). | obligate anaerobe |
| Type of organism that can survive by doing either cellular respiration or fermentation. | facultative anaerobe |
