|---|---|
 Where does it happen? | mitochondria |
| Cristae | increases surface area folds in the inner membrane |
| Martix | liquid in inner membrane |
| first step in cellular respiration | glycolysis |
| glycolysis | 6-carbon molecule to 2 3-carbon molecules does not require oxygen net gain 2 ATP, NADH |
| Where does glycolysis happen? | cytoplasm |
| Aerobic respiration | requires oxygen most efficient in creating ATP |
| Krebs Cycle | 2nd step 3-carbon chains (pyruvate) turn into glucose products: 2 ATP, NADH, FADH2, CO2 |
| Electon Transport Chain | 3rd step use electrons from electron carriers use oxygen products: 32 ATP, H2O |
| electron carriers | NADH FADH2 |
| If no oxygen in aerobic respiration | electrons back up cell dies |
| aerobic respiration steps | glycolysis Krebs Cycle ETC |
| anaerobic respiration steps | glycolysis fermentation |
| two types of fermentation | lactic acid alcoholic |
| lactic acid fermentation | glucose -> lactic acid + 2ATP |
| alcoholic fermentation | glucose -> ethanol + CO2 + 2ATP |
| Is any ATP gained from alcoholic fermentation? | no |
