Cellular Respiration
| Question | Answer |
|---|---|
| Cellular Respiration is: | The process by which cells make ATP from organic compounds. |
| The products of cellular respiration are reactants in what process? | Photosynthesis |
| Chemical formula of cellular respiration | C6H12O6+ 6O2 ---> 6CO2+6H2O+ ATP Energy |
| Both ___ and ___ use cellular respiration. | Autotrophs, Heterotrophs |
| What are the reactants in cellular respiration? | Glucose, Oxygen |
| What are the products of cellular respiration? | Carbon dioxide, Water, ATP Energy |
| What are the two main stages of cellular respiration? | Glycolysis (anaerobic respiration) and aerobic respiration |
| What splits in glycolysis? | Glucose |
| Where does glycolysis occur? | Cytoplasm |
| H taken from glucose and given to NAD+ creates____. | NADH |
| Where does fermentation (anaerobic respiration) occur? | cytoplasm |
| What does anaerobic mean? | without air |
| What type of anaerobic respiration occurs in humans when our cells run out of oxygen? | lactic acid fermentation |
| What is a difference between lactic acid and alcohol fermentation? | Lactic acid molecules are broken to create lactic acid molecules and alcohol fermentation molecules are broken down to make ethyl alcohol and carbon dioxide molecules only |
| What are the two stages of aerobic respiration? | Krebs cycle and electron transport chain (ETC) |
| Where does aerobic respiration (Krebs cycle and ETC) occur? | In mitochondria |
| Where does the Krebs cycle occur? | In the mitochondrial matrix |
| The energy from Krebs Cycle is transferred to____, _____ and ___. | NADH, FADH2 and ATP |
| Energy molecules, including NADH and FADH2, made during the transition reaction and Krebs Cycle, are used in the: | electron transport chain (ETC) |
| Hydrogen ions (protons, H+) move down their concentration and electrical gradients through this enzyme to make ATP: | ATP Synthase |
| How many ATP molecules does the electron transport chain create? | 32 molecules |
| At the end of the ETC, O2 combines with e- and H+ to form: | H2O |
| ATP can be synthesized in the mitochondria only if electrons continue to move along the ___. | Electron transport chain |
| How many ATP molecules does cellular respiration create in total? | 38 (perfect case) |
| What does aerobic mean? | With air |
| Where does the electron transport chain (ETC) occur? | In the inner membrane of the mitochondria |
| In glycolysis and aerobic respiration together, how many molecules of ATP are created by breaking down one molecule of glucose? | 34-36 |
| What type of anaerobic respiration occurs in yeast? | alcoholic fermentation |
| In which part of cellular respiration (glycolysis, Krebs cycle or ETC) is the most ATP made? | ETC |
| Oxygen is necessary for aerobic respiration because: | it is the final electron acceptor in the ETC |
| How many net ATP molecules are made in glycolysis? | 2 |
