Photosynthesis
| Question | Answer |
|---|---|
| autotroph | an organism that produces its own nutrients from inorganic substance or from the environment instead of consuming other organisms |
| Photosynthesis | process used by autotrophs to convert light energy from the sun into chemical energy in the form of organic compounds , primarily carbohydrates |
| heterotrophs | animals and other organisms that must get energy from food instead of directly from sunlight or inorganic substances |
| photosynthesis equation | 6CO2 + 6H2O --> C6H12O6 + 6O2 |
| chloroplasts | organelles found in the cells of plants, algae and some protists |
| thylakoids | a membrane system found within chloroplasts that contains the components for the Light Dependent Reaction of photosynthesis |
| stroma | solution found in the chloroplast, where Light Independent/Calvin Cycle occurs |
| pigments | compounds that absorb light and give color to substances or mixtures |
| chlorophylls | most important pigments in photosynthesis |
| electron transport chain | a series of molecules, found in the inner membranes of mitochondria and chloroplasts, through which electrons pass in a process that causes protons to build up on one side of the membrane |
| Calvin Cycle | series of enzyme-assisted chemical reactions that produces a 3-carbon sugar(glucose), process by which organic compounds are formed using CO2 and the chemical energy stored in ATP and NADPH,also called the Light Independent Reaction, |
| carbon fixation | the incorporation of CO2 into organic compounds takes place in the Calvin cycle/light independent |
| factors that affect photosynthesis | light intensity, CO2 levels, temperature(enzymes denature) |
| chemosynthesis | uses energy released from chemical reactions instead of light energy to produce food for organisms |
| reactants in photosynthesis are | CO2, H2O, O2 |
| products of photosynthesis are | Glucose, oxygen |
| During the light independent reaction, the sun hits the chlorophyll causing H20 to splits into ___________ and _____________. | oxygen and hydrogen O2 is released and H is used to make NADPH |
| NADPH | is an electron carrier and is used in the light independent reaction |
| Light Independent Reaction/Calvin Cycle converts | CO2 and ATP into glucose(sugar) |
