| Question | Answer |
|---|---|
| adenosine triphospate (ATP) | adenosine molecule with three phosphate groups attached |
| adenosine monophosphate (AMP) | adenosine molecule with one phosphate group attached |
| adenosine diphosphate (ADP) | adenosine molecule with two phosphate groups attached |
| photosynthesis | process that uses the sun's energy to make simple sugars |
| light-dependent reactions | phase of photosynthesis that converts light energy into chemical energy in the form of ATP; results in the splitting of water and the release of oxygen |
| light-independent reactions | phase of photosynthesis where energy from light-dependent reactions is used to produce glucose and additional ATP molecules |
| pigments | molecules that absorb specific wavelengths of sunlight |
| chlorophyll | absorbs most wavelengths of light except green; gives leaves a green appearance |
| electron transport | series of proteins embedded in the thylakoid membrane |
| photolysis | water molecules are split in the first photosystem to replace lost electrons |
| Calvin cycle | second phase of photosynthesis; does not require light; series of reactions that use carbon dioxide to form sugars |
| cellular respiration | process by which mitochondria break down food molecules to produce ATP |
| anaerobic | no oxygen required |
| aerobic | requires oxygen |
| glycolysis | series of chemical reactions in the cytoplasm of a cell that break down glucose, a six-carbon compound, into tow molecules of pyruvic acid, a three-carbon compound |
| citric acid cycle | also called the Krebs cycle; series of chemical reactions similar to the Calvin cycle |
| alcoholic fermentation | used by yeast cells and some bacteria to produce CO2 and ethyl alcohol |
| lactic acid fermentation | process that supplies energy when oxygen is scarce |
