| passive transport (energy use) | movement of molecules that requires no energy from the cell |
| active transport (energy use) | movement of molecules that requires energy from the cell |
| active transport | used to move molecules from an area of low concentration to an area of high concentration |
| osmosis | movement of water from an area of high concentration to an area of low concentration |
| diffusion | movement of any type of molecule other than water from an area of high concentration to an area of low concentration |
| photosynthesis (where) | takes place in the chloroplast |
| photosynthesis (what) | process by which plants use energy in sunlight and materials in air and water to make glucose |
| photosynthesis (chemical equation) | 6CO2 + 6H2O + light energy = C6H12O6 + 6CO2 |
| respiration (where) | takes place in the mitochondria |
| respiration (what) | release of stored energy in glucose; glucose is combined with O2 to break it down into a simpler substance (ATP) |
| respiration (chemical equation) | C6H12O6 + 6O2 = 6CO2 + 6H2O +energy (ATP) |
| ATP | adenosine triphosphate |
| fermentation | breakdown of glucose into carbon dioxide, either lactic acid or alcohol, and a small amount of ATP without the use of oxygen |
