| Question | Answer |
|---|---|
| Calvin Cycle | A series of enzyme-assisted chemical reactions that produces a three-carbon sugar. |
| Carbon fixation | The incorporation of CO2 into organic compounds |
| Stoma | small pores in plants and are the major passageways through which CO2 enters and O2 leaves a plant. |
| C4 Pathway | Enables certain plants to fix CO2 into four-carbon compounds |
| CAM Pathway | Crassulacean acid metabolism. A water-conserving pathway. |
| The calvin cycle begins when CO2 combines with a five carbon carbohydrate called | RuBP |
| For every three molecules of CO2 that enter the calvin cycle, the cycle produces six molecules of | 3-PGA |
| Organic compounds that can be made from the products of the Calvin Cycle include | Carbohydrates, amino acids, and lipids |
| C3 and C4 plants differ in terms of the number of | Carbon atoms in the compound that CO2 is initially incorporated to |
| As light intensity increases, the rate of photosynthesis | increases |
| How many molecules of ATP and NADPH are used in one turn of the Calvin cycle | 9 ATP and 6 NADPH |
| Simplest overall equation for photosynthesis | CO2 + H2O -----> (CH2O) + O2 |
| In the second set of reactions in photosynthesis, plants use the energy that was stored in ATP and NADPH during the light reactions to produce________ | organic compounds in the form of sugars. |
| The most common way that plants produce organic compounds is called the ______ | Calvin cycle. |
| Many plant species that evolved in hot, dry climates fix carbon through __________ | alternative pathways. |
| Three factors with the most influence on photosynthesis are? | light intensity, CO2 level, and temperature. |
