|
Term
|
Definition
| Conversion of light energy to chemical energy that is stored in sugars or other organic compounds; occur in plants, algae, and certain prokaryotes |
|
|
Term
|
Definition
| first two major stages in photosynthesis. occur on the thylakoid membranes of chloroplast or on membranes of certain prokaryotes, convert solar energy to the chemical energy of ATP and NADPH, releasing oxygen in the process |
|
|
Term
|
Definition
| The second stage of photosynthesis, not requiring light to occur, and during which energy released from ATP drives the production of organic molecules from carbon dioxide. |
|
|
Term
| electromagnetic radiation |
|
Definition
| Electromagnetic radiation (often abbreviated E-M radiation or EMR) is a form of energy exhibiting wave like behavior as it travels through space. EMR has both electric and magnetic field components, which oscillate in phase perpendicular to each other and perpendicular to the direction of energy propagation. |
|
|
Term
|
Definition
| A quantum, or discrete quantity, of light energy that behaves as if it were a particle |
|
|
Term
|
Definition
| a material that changes the color of reflected or transmitted light as the result of wavelength-selective absorption |
|
|
Term
|
Definition
| A green pigment located within the chhloroplasts of plants and algae and in the membranes of certain prokaryotes, A participates directly in the light reactions, which convert solar to chemical energy |
|
|
Term
|
Definition
| excited state: state in which an atom or molecule picks up outside energy, causing an electron to move into a higher-energy orbital. |
|
|
Term
|
Definition
| its lowest-energy state; the energy of the ground state is known as the zero-point energy of the system. |
|
|
Term
|
Definition
| the emission of light by a substance that has absorbed light or other electromagnetic radiation of a different wavelength |
|
|
Term
|
Definition
| light capturing unit located in the thylakoid membrane of the chloroplast, consisting of a reaction center complext surrounded by numerous light harvesting complexes, 2 types: 1 and 2, absorb light best at diff wavelengths |
|
|
Term
|
Definition
| complex of proteins associated with pigment molecules, that captures light energy and transfers it to reaction center pigments in a photosystem |
|
|
Term
|
Definition
They are the light pigments that capture light in ranges other than chlorophyll a and passes this light energy on to chlorophyll a at the reaction center.

Term
|
Definition
| In plants, NADP is reduced in the last step of the electron chain of the light reactions of photosynthesis. The NADPH produced is then used as a reducing agent in the Calvin cycle of photosynthesis. |

Term
|
Definition
| ribulose bisphosphate carboxylase, enzyeme that catalyzes the first step of the calvin cycle |
|
|
Term
| glyceraldehyde 3 phosphate |

Definition
| a 3 carbon carb that is a direct product of the calvin cycle, it is also an intermediate in glycolysis |
|
|
Term
|
Definition
| initial incorporation of carbon from co2 into an organic compound by an autotrophic organism |
