Definition
| An organism that utilizes either photosynthesis or chemosynthesis to produce its own organic food from inorganic CO2. |
|
|
Term
|
Definition
| The series of biochemical reactions that occur in the stroma and utilize carbon dioxide and ATP and NADPH from the light-independent reactions to produce glucose. |
|
|
Term
|
Definition
| Main pigment of photosynthesis. Maximizes absorption in the red and blue wavelengths of the spectrum and reflects the green wavelenghts back to the observer. |
|
|
Term
|
Definition
| Maximizes absorbtion in the red and blue wavelengths so as to complement the absorption of chlorphyll a. |
|
|
Term
|
Definition
| The spectrum of radiation based on the inverse relationship between wavelength and frequency. Gamma rays possess the shortest wavelength and radio waves possess the longest wavelength. |
|
|
Term
|
Definition
| The three-carbon carbohydrate directy produced by the Calvin cycle and used to build glucose. |
|
|
Term
|
Definition
| The biochemical pathway that converts sunlight into chemical energy in the form of ATP and NADPH |
|
|
Term
|
Definition
| The energy shuttle generated by the light reactions and used by the Calvin cycle to help produce glucose. |
|
|
Term
|
Definition
| The cheiosmotic process by which ATP is generated as an H+ ion diffuses across the thylakoid membrane via ATP synthase. |
|
|
Term
|
Definition
| A metabolic pathway employed on dry, hot days when stomata close and leaf concentrations of O2 exceed CO2. |
|
|
Term
|
Definition
| The biochemical pathway utilized by photoautotrophs to produce carbohydrate monomers from carbon dioxide and water. Equation-- 6CO2 + 6H2O + sunlight --> C6H12O6 + 6H2O |
|
|
Term
|
Definition
| A collection of pigments in the thylakoid membrane of the chloroplast that absorbs light. |
|
|
Term
|
Definition
| Contains P700 chlorophyll a at its reaction center. Directly connected bia electron transport chains to photosystem II and to the production of NADPH |
|
|
Term
|
Definition
| Contains P680 chlorophyll a at its reaction center. Accepts electrons from the splitting of water and directs them down an electron transport chain toward photosystem I. |
|
|
Term
| primary electron acceptor |
|
Definition
| The first electron acceptor of the electron transport chain that starts a series of redox reactions. |
|
|
Term
|
Definition
| The area in the photosystem concentrated ith chlorophyll a toward which all of the absorbed energy from light is directed form the accessory pigments. |
|
|
Term
|
Definition
| The enzyme that catalyzes the reaction between CO2 and RuBP to start the Calvin cycle. |
|
|
Term
|
Definition
| The five-carbon compound used to incorporate CO2 into an organic compound in the first step of the Calvin Cycle. |
|
|
Term
|
Definition
| The space inside the inner membrane of the chloroplast surrounding the grana. The site of the Calvin Cycle. |
|
|
Term
|
Definition
| The disc-shaped folds of the inner membrane of a chloroplast arranged in stacks called grana. The sight of the light reactions. |
|
|
Term
|
Definition
| The region on the electromagnetic spectrum where wavelengths range from 380 nm to 750 nm. |
|
|
Term
|
Definition
| The distance from one peak of a wave to the next. |
|
|
Term
|
Definition
| A plant that uses crassulacean acid metabolism, a specialized adaptation found in desert plants that allows for collection and storage of CO2 at night when water loss is minimized. During the day, when stomata aare closed, the CO2 is released from storage and used in the calvin cycle. |
|
|
Term
|
Definition
| A plant that incorporates CO2 first into a four-carbon compound and, ultimately, into the calvin cycle. Allows for increased water efficiency by highly regulating opening and closing of stomata. |
|
|
Term
|
Definition
| A plant that directly incorporates CO2 into the Calvin cycle. |
