| autotroph | organism that gets energy directly from the sun or organic molecules |
| photosynthesis | process where plants use the sun's energy to convert H2O and CO2 into sugars |
| producer | autotroph |
| heterotroph | organism that obtains energy by eating other organisms |
| consumer | organism that obtains by eating producers (autotrophs) or other consumers |
| cellular respiration | process that converts chemical energy stored in organic molecules into ATP |
| kinetic energy | energy of motion |
| potential energy | energy stored due to an object's position or arrangement |
| thermal energy | total amount of energy associated with the random movement of atoms and molecules |
| chemical energy | potential to perform work due to the arrangement of atoms within molecules |
| calorie | amount of energy required to raise the temperature of 1 g of water 1°C |
| ATP | Adenosine triphosphate; molecule cells use to run their cell reactions |
| aerobic | requiring oxygen |
| electron transport chain | last step of cellular respiration; oxygen is required; 32 ATP made |
| metabolism | all of a cell's chemical processes |
| glycolysis | first stage of cellular respiration and fermentation; glucose is split |
| Krebs cycle | second stage in cellular respiration; lots of electrons are made |
| fermentation | cellular process of making ATP without oxygen |
| anaerobic | without oxygen |
| reactants in cellular respiration | glucose and oxygen |
| products in cellular respiration | ATP, water, carbon dioxide |
| mitochondria | organelle where ATP is made during cellular respiration |
