Cellular Respiration
| Question | Answer |
|---|---|
| Cellular Respiration def. | process of releasing energy (ATP) from organic molecule |
| Products of cellular respiration are reactants in what? | Photosynthesis |
| Chemical Formula of cellular respiration | C6H12O6+ 6O2>> 6CO2+6H2O+38 ATP |
| Both ___ and ___ use cellular respiration. | Autotrophs: Heterotrophs |
| What are reactants in Cellular Respiration? (In) | Glucose, 2 ATP, 2 NAD+, 4 ADP |
| What are products of Cellular Respiration | Pyruvate acid, 2 ADP, 2 NADH, 4ATP |
| What are the two stages of cellular respiration? | Glycolysis (anaerobic) and Aerobic respiration |
| What splits in glycolysis? | Glucose |
| Where does glycolysis occur? | Cytoplasm |
| What is the gross amount of ATP molecules produced? | 4 ATP molecules |
| What is the net amount of ATP molecules produced? | 2 ATP molecules |
| H taken from glucose and given to NAD+ creates____. | NADH |
| Where does fermentation occur? | cytoplasm |
| What does anaerobic mean? | without air |
| When did fermentation evolve? | When the Earth's atmosphere had no oxygen |
| What does lactic acid make? | cheese |
| What does Alcohol fermentation create? | bread |
| Pyruvic acid is converted to___. | ethyl alcohol |
| 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 glycolysis? | Lactic acid and alcohol fermentation |
| What are the two stages of Aerobic Respiration? | Kreb Cycle and Electron transport chain |
| where does Aerobic respiration occur? | In mitochondria only if there is oxygen |
| Reactants of aerobic respiration | 2 pyruvate molecules, 2 ATP, and 2 NADH |
| Products of Aerobic respiration | Glucose, 2 ADP, 2 NAD+ |
| Where is Acetyl CoA formed? | In the mitochondrial matrix |
| Where does the Krebs cycle occur? | In the mitochondrial matrix |
| For every glucose molecule, the Krebs cycle moves around twice producing a total of | 4 CO2, 2ATP, 6 NADH, 2 FADH2 |
| 1 glucose molecule is completely broken down in two turns of the ___. | Krebs Cycle |
| The bulk of the energy released by the oxidation of glucose still has not been transferred to ___. | ATP |
| The energy from Krebs Cycle has been transferred to____ and ___ | NADH and FADH2 |
| NADH and FADH2 from glycolysis, transition reaction, and Krebs Cycle move to the ___ | ETC |
| ATP is a produced through____. | Chemiosmosis |
| H+ move down their concentration and electrical gradients through ___ ________. | ATP Synthase |
| How many ATP molecules does the electron transport chain create? | 32 molecules |
| O2 combines with e- and H+ to form ___? | H2O |
| ATP can be synthesized by chemiosmosis only if electrons continue ti move along the ___. | Electron transport chain |
| How many ATP molecules does cellular respiration create in total? | 38 |
| Aerobic cellular respiration is nearly __ times more efficient that glycolysis alone. | 20 |
