Term | Definition |
---|---|
Phosphorylation | The transfer of energy when a phosphate group is moved between molecules |
Pigment | An organic compound that reflects specific light wavelengths producing color |
Chlorophyll | A group of pigments found in green plants, algae, and cyanobacteria that is necessary for photosynthesis |
Stroma | Gel-like fluid found inside the inner membrane of chloroplasts |
Thylakoid | Disk-shaped sac suspended in the stroma of chloroplasts. It is the site of the light reactions of photosyntesis |
Grana | Stacks of thylakoids |
Photosystem | A cluster of chlorophyll and other molecules, in the thylakoid membrane, that absorb light energy |
Electron transport chain | A series of electron carrying molecules within a membrane that transfer electrons and release energy at each transfer |
Aerobic | Requiring oxygen |
Anaerobic | Without oxygen |
Glycolysis | The first stage of cellular respiration where glucose is split in half. |
Krebs cycle | The second stage of cellular respiration where CO2 is used to complete the breakdown of pyruvic acid molecules, releasing energy |
Fermentation | A cellular process producing ATP without oxygen |
