|---|
| glycolysis | the breaking apart of one glucose molecule into two pyruvate molecules and making 2 ATP; the first stage of cellular respiration |
| cristae | the folded inner membrane of the mitochondria where the electron transport chain occurs and ATP is made |
| matrix | the liquid filled space between the folds of the inner membrane in the mitochondria where the Kreb's Cycle occurs |
| FADH2 | a molecule that carries high energy electrons only inside the mitochondria |
| NADH | a molecule that carries high energy electrons from the cytoplasm into the mitochondria and within the mitochondria |
| electron transport chain | the process that moves energized electrons from one protein molecule to another on the cristae membrane to make ATP; the final stage of aerobic respiration |
| Kreb's Cycle | the process that breaks pyruvate down and produces carbon dioxide and energized electrons; the second stage of aerobic respiration |
| aerobic respiration | cellular respiration that requires oxygen |
| anaerobic respiration | cellular respiration that does not need oxygen |
| alcohol fermentation | the type of anaerobic respiration that produces ethanol and carbon dioxide as well as 2 ATP |
| lactic acid fermentation | the type of anerobic respiration performed by yogurt-making bacteria and human muscle cells which produces lactate and 2 ATP |
