| Term | Definition |
|---|
| cytoplasm | the place where it all begins |
| glycolysis | the process that begins breaking down glucose into 2 pyruvates ( each a 3 carbon compound) , and creating a small amount of ATP (4) |
| Kreb's Cycle | If oxygen is present, then the pyruvate made during glycolysis is moved to the mitochondria and enter this cycle in which CO2 is released, a small amount of ATP is created (2), and the electrons and hydrogen ions go to acceptors |
| electron transfer chain | where the electrons spun off from the Kreb's Cycle enter to create a lot of ATP |
| water | what is formed when the electrons and hydrogen ions meet up with oxygen |
| fermentation | If oxygen is not present, this pathway is used to break down glucose |
| alcoholic | in this type of fermentation, occurring in bacteria and yeast, water is used to make CO2 and ethanol, and only 2 ATP's |
| lactic acid | in this type of fermentation, occurring in animal cells, lactate is produced when there is not enough O2 present, only 2 ATP's, and NAD+ is used to keep the process going slowly |
