Order by
17 terms
Terms | Definitions |
|---|---|
 photosynthesis | the process by which plants, algae, and some bacteria use sunlight, CO2, and H2O to produce glucose & oxygen |
| autotrophs | organisms that perform photosynthesis |
| cellular respiration | the process by which cells produce energy by breaking down glucose |
| ATP | molecule that acts as the main energy source for cell processes |
| pigments | A substance that absorbs certain wavelengths (colors) of light and commonly reflects all others |
| chlorophyll | green pigment found in plants that absorbs sunlight and uses its energy to synthesize glucose from CO2 and H2O |
| chloroplasts | part of the plant where photosynthesis takes place |
| respiration | The exchange of oxygen and carbon dioxide between living cells and their enviornment |
| Anaerobic Respiration | metabolic process that does not require the presence of oxygen |
| Aerobic Respiration | metabolic process that does require the presence oxygen |
| Cellular Respiration | the breaking down of food (organic compounds) to release energy |
| Glycolysis | process of breaking down glucose into pyruvic acid |
| Krebs Cycle | part of an aerobic process that breaks down pyruvic acid into electron carriers |
| Calvin Cycle | cycle in photosynthesis in which carbon dioxide is converted into glucose |
| fermentation | the breakdown of glucose by enzymes, bacteria, and yeasts, or mold in the absence of oxygen |
| Electron Transport System | The remaining energy from glucose from the Krebs cycle comes to this cycle as electron carriers and bindswith Hydrogen to make ATP and H2O |
| ATP Synthase | enzyme that can synthesize adenosine triphosphate (ATP) from adenosine diphosphate (ADP) and inorganic phosphate by using some form of energy |
