- Thylakoids
- clusters of pigment embedded in the membranes of disk-shaped structures
- Electron Transport Chains
- series of molecules through which excited electrons are passees along a thylakoid membrane
- Glycolysis
- glucose is broken down in the cytoplasm
- Krebs Cycle
- process by which sugar is made
- Anaerobic
- metabolic process that don't require oxygen
- Aerobic
- metabolic processes that require oxygen
- FADH2
- type of electron carrier
- Autotrophs
- organisms that use energy from sunlight or from chemical bonds in inorganic substances to make organic compounds
- Heterotrophs
- organisms that must get energy from food instead of directly from sunlight or inorganic substances
- Carbon Dioxide Fixation
- the transfer of carbon dioxide to organic compounds
- NAPH
- electron carrier that provides the high-energy electrons needed to make carbon-hydrogen
- Pigments
- light absorbing substances
- Carotenoids
- absorbs wavelenghts of light doifferent from those absorbed by chlorophyl
- Chlorophyl
- absorbs mostly blue and red light and reflects green and yellow light
- Photosynthesis
- process by which light energy is converted to chemical energy
- NADH
- as glucose is broken down some of its hydrogen atoms are transffered to an electron acceptor
- Fermentation
- the recylcling of NAD+ using an organic hydrogen acceptor
- Cellular Respiration
- releases much of the energy in food to make ATP
