|
Definition
| the chlorphyll in the protein channel |
|
|
Term
|
Definition
where the CO2 goes in C3 plants
-tissue that surrounds the vein in plant cells
-contain chloroplast in c4 planta |
|
|
Term
|
Definition
close stomata during hot weather rely on photorespiration to make Co2 from O2
-has abundant rubisco in palisade cells
-photosynthesis in mesophyll |
|
|
Term
|
Definition
close stoma, but doesnt use photorespiration
-uses PEP carboxylase, advantage is doesnt require oxygen
-mesophyll and bundle sheath
CO2 accepted by PEP to make oxaloacetate, oxaloacetate diffuses to bundle sheath cells which has abundant rubisco, oxaloacetate is decarboxylated ( PEP return to mesophyll cells and CO2 enter calvin cycle) |
|
|
Term
|
Definition
occurs in the stroma
-CO2 rxn w/ RuBP, RuBP--> 3PG, 3PG--> sugar, and while other products are release
calvin cycle products: ADP & NADP+ |

Definition
accesory pigment
-yellow,orange,red pigment |
|
|
Term
|
Definition
pigment
-reflect green light
-in PS II and PSI
- mg2+ center atom, hydrocarbon tail
-form antenna system, obsrob the photom and pass on excited e- |
|
|
Term
| CAM ( crassulacean acid metabolism) |
|
Definition
metabolic pathway allowing plants to store CO2 at night and preforming photosynthesis during the day
-open stomata at night |
|

Term

Definition
protien in e- transport chain
cyclic cycle
e-transport back to e- transport chain and genereate atp |
|
|
Term
|
Definition
-excitement of e-
-chlorophyll absorb light
e- transport chain
h20 molecule use to replenish e- loss in excitement of e- in chlorophyll PS II-->
plastoquinone---> cytochrome--->plastocyanin--->PS I---> ferrodoxin---> NADP reductase
-charbohydrates are not produce during light reaction of photosynthesis
products: ATP & NADPH for the calvin cycle |
|
|
Term
| light independent reaction ( dark reaction) |
|
Definition
calvin cycle:
carbon fixation
- in non cyclic cycle the rxn goes all the way to NADP+ reductase
reduction and sugar production
-regeneration of RuBP
-stimulated by light, so dependent on light rxn |
|
|
Term
|
Definition
chlorplast containing photosynthetic cells in the interior of the leave
-most active in a plant cell during photosynthesis
-palisade mesophyll cell, does most of the photosynthesis
-spongy mesophyll cell: faciliate gases to the palisade cell, cuz of its loose structure |
|
|
Term
|
Definition
product of the cavlin cycle
use to transport e-
-reduce by ferredoxin - NADP+ reductase in light rxn |
|
|
Term
|
Definition
| any enzyme that oxidizes a substrate by transferring the oxygen from molecular oxygen O2 (as in air) to it |
|
|
Term
|
Definition
in c4 plants
-combine with CO2 to make oxaloacetate, a four carbon structure
-In succulent CAM plants adapted for growth in very dry conditions, PEP carboxylase fixes CO2 during the night when the plant opens its stomata to allow for gas exchange. |

Term
|
Definition
| process of using light to create atp |
|
|
Term
|
Definition
using O2 to make CO2
glycolate---> peroxisome ( convert to glycine)--->glycine diffuse to mitochondria---> in mitochondria, 2 glycine ---> glycerate + CO2
-more likely at higher temperatures |
|
|
Term
|
Definition
accesory pigment
- found in cyanobacteria and in the chloroplasts of red algae, glaucophytes and some cryptomonads (though not in green algae and higher plants)
-efficient at absorbing red, orange, yellow and green light, wavelengths which are not well absorbed by chlorophyll a. |

Term

Definition
protien in e- transport chain
-3rd protein in e- transport chain |
|
|
Term
|
Definition
protein in e- transport chain
-first protein in e- transport chain |
|
|
Term
|
Definition
| an important substrate involved in carbon fixation. The enzyme (RuBisCO) catalyzes RuBP with carbon dioxide in order to synthesize a highly unstable 6-carbon intermediate which decays virtually instantaneously into two molecules of glycerate 3-phosphate (G3P) |
|
|
Term
|
Definition
-occur when a molecule returns to ground state
-it is light energy weaker than the light energy it absorb
-no chemical work is done |
