| the step of respiration where water is formed | electron transport chain |
| the step of respiration where FAD becomes FADH2 | Krebs cycle |
| the step of respiration that creates pyruvate | glycolysis |
| process that allows glycolysis to occur when oxygen is not present | fermentation |
| how many ATP are made in the process of respiration | 36-38 |
| how many ATP are made by glycolysis | 2 |
| products of alcoholic fermentation | alcohol and carbon dioxide |
| products of lactic acid fermentation | lactic acid |
| which step of respiration creates acetyl CoA | prep reaction |
| location in the cell where glycolysis takes place | cytoplasm |
| location in the cell where Krebs cycle takes place | mitochondrial matrix |
| location in the cell where electron transport chain takes place | mitochondrial intermembrane |
| phase of the cell cycle where DNA is replicated | interphase (S stage) |
| phase of the cell cycle where the cell grows, carries out normal functions and doubles its organelles | interphase (G1 stage) |
| nuclear division | mitosis |
| division of the cytoplasm | cytokinesis |
| programmed cell death | apoptosis |
| body cells | somatic |
| sex cells | germ/gametes |
