| Term | Definition |
|---|---|
| aerobic respiration | a process that produces cellular energy in the presence of oxygen |
| adenosine triphosphate (ATP) | energy-carrying biological molecule that drives cellular activities when broken down |
| anaerobic respiration | process that produces cellular energy without oxygen |
| cell membrane | a double layer of lipids and proteins that surrounds a cell and separates the cytoplasm from its surrounding environment |
| cellular respiration | a catabolic pathway in which organic molecules are broken down to release energy in the form of ATP for use by the cell |
| eukaryotic | a cell with membrane-bound nucleus and organelles that is generally larger and more complex |
| mitochondria | a membrane-bound organelle that converts fuel into energy that is available to the rest of the cell |
| photosynthesis | the process by which plants, algae, and some bacteria convert radiant energy from the sun into chemical energy |
| prokaryotic | a cell without a nucleus or other membrane-bound organelles |
