Cellular Respiration
Unit 5- 10.1 Notes
| Question | Answer |
|---|---|
| Where do organisms get their energy from? | food |
| When is energy released from cells? | when chemical bonds are broken |
| What is the unit for energy in food? | calorie |
| What is a calorie? | the amount of energy needed to raise the temp of 1 gram of water 1 degrees celsius |
| What contains the most calories? | fats |
| What is cellular respiration? | a process of energy conversion that releases energy from food in the presence of oxygen |
| How many stages of cellular respiration is there? | 3 (Glycolysis, Krebs cycle, Electron Transport) |
| Where does glycolysis occur? | in the cytoplasm |
| What does glycolysis make? | products needed for other stages |
| Does glycolysis need oxygen? | no |
| What is "anaerobic"? | does not require oxygen |
| Where does the Krebs cycle occur? | in the mitochondria |
| What does the Krebs cycle make? | lots of electron carriers (for next stage) |
| Does the Krebs cycle directly require oxygen? | no |
| What is the Electron Transport Chain responsible for? | converting most of the energy into ATP |
| Where does the Electron Transport Chain take place? | in the mitochondria |
| Does the Electron Transport Chain require oxygen? | yes |
| What is "aerobic"? | requires oxygen |
| What is the relationship between photosynthesis and cellular respiration? | the products of one become the reactants of the other |
