Cell Respiration
ES Cell Respiration
| Question | Answer |
|---|---|
| The breakdown of a food substance into usable cellular energy in the form of ATP is called | cellular respiration |
| This requires oxygen; its the opposite of photosynthesis | aerobic respiration |
| While photosynthesis combines H2O, CO2 and light E to form glucose, this breaks down glucose to form water, CO2 and E (in the form of ATP) | aerobic respiration |
| This is one of the most efficient energy processes known | aerobic respiration |
| This does not need O2, but is the first step in the breakdown of glucose to make 2 pyruvic acid molecules | glycolysis |
| Glycolysis takes place in this part of the cell | cytoplasm |
| Citric acid cycle yields 2ATP + | FADH2 + NADH |
| Hydrogen & Electron transport system yields | 32 ATP |
| Aero means | air |
| Bic or bio means | life |
| An means | without |
| This does not require O2 | anaerobic respiration |
| 2 types of anaerobic respiration | lactic acid fermentation, alcoholic fermentation |
| This is the breakdown of food (usually glucose) with O2, it begins with glycolysis to yield 2ATP; resulting pyruvic acid converts to this | lactic acid fermentation |
| This begins with glycolysis to yield 2 ATP, resulting pyruvic acid converts to this, and CO2 is a by-product | alcoholic fermentation |
| used by the bacteria that make liquors and by yeast to make bread | alcoholic fermentation |
| Cell respiration can be either ...... (which requires oxygen) or .......(which does not require oxygen) | aerobic, anaerobic |
| Cellular respiration is the breakdown of ....... to yield usable cellular energy in the form of ....... | glucose, ATP |
| This is the opposite of photosynthesis | aerobic cellular respiration |
| This results in stored energy in the form of glucose | aerobic cellular respiration |
| What is the formula for photosynthesis | H2O + CO2 + light energy --chlorophyll---> C6H12O6 + O2 |
| What is the formula for aerobic cellular respiration | C6H12O6 + O2 ---> H2O + CO2 + ATP (energy) |
| The most common path of aerobic cellular respiration involes 3 things: | 1.glycolysis, 2. the citric acid cycle or Krebs cycle, 3.hydrogen & electron transport system |
| Glycolysis, the citric acid cycle or Krebs Cycle and the hydorgen & electron transport system together cause the breakeown of a ........ molecule to form water, carbon dioxide, and ........ energy | glucose, ATP |
| Formula for glycolysis | glucose + 2ATP --enzymes---> 2 pyruvic acide + 4 ATP + NADH |
| Formula for citric acid cycle | 2 pyruvic acid ---> 2ATP |
| What does the breakdown of the pyruvic acid, formed in glycolysis, yield? | hydorgen and electon transport system |
| With the addition of O2 in the hydrogen and electron transport system, there is a yield of ....ATP as a result of this phase of aerobic cellular respiration | 32 |
| Anaerobic Cellular respiration called fermentation can occur by either .......... or by ................ | lactic acid fermentation, alcoholic fermentation |
| Aerobic respiration is a more efficient producer of energy than | cellular fermentation |
