what is being oxidized in the photosynthesis equation? - CORRECT
| | | | | | | | | |
ANSWER✔✔-H2O ---> O2 | |
,who is the electron donor? - CORRECT ANSWER✔✔-water; oxygen is
| | | | | | | | | |
transformed as a by product | | | |
photosynthetic electron transport chain - CORRECT ANSWER✔✔-series | | | | | | |
of reactions that links oxidation of water to reduction of carbon dioxide
| | | | | | | | | | |
where is the electron transport chain located? - CORRECT ANSWER✔✔-
| | | | | | | | |
the thylakoid membrane
| |
where does the light cycle occur? - CORRECT ANSWER✔✔-the grana
| | | | | | | | |
calvin cycle - CORRECT ANSWER✔✔-sugars are synthesized from CO2
| | | | | | | |
calvin cycle requires: - CORRECT ANSWER✔✔-two molecules of NADH
| | | | | | | | |
and three molecules of ATP for each CO2 incorporated into
| | | | | | | | | |
carbohydrates
steps of the Calvin cycle - CORRECT ANSWER✔✔-1. carboxylation
| | | | | | | |
2. reduction
|
3. regeneration
|
carboxylation - CORRECT ANSWER✔✔-CO2 +(rubisco)+ RuBP = 2(3-PGA)
| | | | | | |
,-the addition of CO2 to the 5-carbon compound RuBP
| | | | | | | |
rubisco - CORRECT ANSWER✔✔-catalyzes carboxylation reaction which
| | | | | | |
originally would take a long time
| | | | |
reduction (in Calvin cycle) - CORRECT ANSWER✔✔-3-PGA---(ATP and
| | | | | | | |
NAPH)----> triode phosphate | |
-NADPH transfers two electrons and one proton; inorganic phosphate is
| | | | | | | | | |
released
regeneration - CORRECT ANSWER✔✔-triose phosphate -------(ATP)---->
| | | | | |
RuBP ---> beginning of cycle
| | | |
-(regeneration of RuBP) a multistep process where 3-carbon compounds
| | | | | | | |
are reorganized and combined to produce RuBP
| | | | | | |
light reaction - CORRECT ANSWER✔✔-water is broken apart in the
| | | | | | | | | |
chlorophyll molecule into H+ and OH- ions in the presence of light,
| | | | | | | | | | | |
resulting in the formation of NADPH and ATP
| | | | | | |
, photosystems - CORRECT ANSWER✔✔-PSI and PSII; protein-pigmented | | | | | | |
complexes; the functional and structural unit that absorbs light energy
| | | | | | | | | |
and uses it to drive electron transport
| | | | | |
chlorophyll light absorption - CORRECT ANSWER✔✔-z-scheme;
| | | | | |
absorption of visible light by an antenna chlorophyll results in the
| | | | | | | | | | |
transfer of energy to an electron in a neighboring chlorophyll molecule
| | | | | | | | | |
reaction center - CORRECT ANSWER✔✔-configured pair of chlorophyll
| | | | | | | |
molecules where energy is transfered to, then converted to chemical
| | | | | | | | | |
energy (from antennae chlorophyll)
| | |
PSII - CORRECT ANSWER✔✔-energizes electrons to the beginning go the
| | | | | | | | |
electron transport chain; when it loses an electron, it is able to pull
| | | | | | | | | | | | | |
electrons from water | |
PSI - CORRECT ANSWER✔✔-energizes electrons with a second input of
| | | | | | | | | |
light energy so that they can be used to reduce NADP+
| | | | | | | | | |
cytochrome-b6f complex - CORRECT ANSWER✔✔-where electrons pass | | | | | | |
between photosystems |
cyclic electron transport - CORRECT ANSWER✔✔-electrons from PSI are
| | | | | | | | |
redirected from ferredoxin back into the electron transport chain
| | | | | | | |
