Cell Energy
ATP, Photosynthesis & Respiration
| Term | Definition |
|---|---|
| Cellular Respiration | The process of breaking down glucose to release the energy or ATP that cells need to perform their functions. Takes place in the mitochondria of both plant and animal cells. |
| Photosynthesis | The process of using the sun's energy to make glucose or sugar, which occurs only in the plant cell's chloroplast. |
| Interdependence | When two or more processes, or organisms, rely on one another. Example: photosynthesis & respiration occur in a cycle---one cannot happen without the other. |
| Reactant | materials required to perform a chemical reaction. Also known as the Inputs. |
| Product | the end result of a chemical reaction; it is what is made during a chemical reaction. Also known as the Outputs |
| ATP | Adenosine Triphosphate. 1 adenine, 1 ribose sugar and 3 phosphates. Like a fully charged battery |
| ADP | Adenosine Diphosphate. 1 adenine, 1 ribose sugar and 2 phosphates. Like a dead battery. |
| C6H12O6 | Glucose |
| 02 | Oxygen |
| CO2 | Carbon Dioxide |
| H2O | Water |
| Byproduct | waste product. made, but not used |
| Aerobic Respiration | cellular respiration in the presence of oxygen. the most efficient type, which makes 32-28 ATP |
| Anaerobic Respiration | cellular respiration WITHOUT oxygen. totally inefficient. only makes 2 ATP. |
| Light Reactions | a part of Photosynthesis that takes place in the Thylakoid membrane inside the Chloroplast. Requires sunlight and water and produces Oxygen as a byproduct. |
| Calvin Cycle or Dark Reactions or Light Independent Reaction | a part of Photosynthesis that takes place in the Stroma inside the Chloroplast. Requires Carbon Dioxide & ATP & produces Glucose. |
| Glycolysis | a part of Cellular Respiration. Occurs in the cytoplasm OUTSIDE of the Mitochondria. Requires Glucose & Pyruvate & produces only 2 ATP & CO2 as a byproduct. |
| Krebs Cycle or Citric Acid Cycle | a part of Cellular Respiration. Occurs INSIDE the Mitochondria. Produces 2 ATP & CO2 as a byproduct |
| Electron Transport Chain | a part of Aerobic Cellular Respiration. Occurs INSIDE the Mitochondria. Requires O2 & produces 32-34 ATP & H2O as a byproduct. |
