| A | B |
|---|
| ADP | combined with a phosphate group to form ATP |
| ATP | the main energy molecule of the cell |
| aerobic | requires oxygen |
| anaerobic respiration | takes place without oxygen |
| autotroph | organism that makes its own energy |
| heterotroph | organism that consumes other organisms for energy |
| chlorophyll | green pigment that absorb light energy |
| chloroplast | photosynthesis takes place in this organelle |
| mitochondria | powerhouse of the cell that makes ATP |
| light-independent reactions | uses NADPH and ATP to rearrange carbon dioxide into glucose |
| light-dependent reactions | uses light energy to make NADPH and ATP |
| Calvin cycle | uses the products of the light reactions to make glucose |
| Krebs cycle | second stage of cellular respiration |
| photosynthesis | use light energy to convert carbon dioxide and water to glucose and oxygen gas |
| cellular respiration | convert glucose and oxygen to ATP, carbon dioxide and water |
| glycolysis | split one glucose into two molecules |
| electron transport chain | requires oxygen and generates the most ATP |
| fermentation | replace compounds needed for glycolysis |
| products | substances that come out of a process |
| reactants | substances that go into a process |
