Definition
| series of pigments and electron carriers/proteins= ETC |
|
|
Term
|
Definition
photosystem 2 and one
Z pathway |
|
|
Term
|
Definition
| (PS II) anaerorebic- no oxygen evolved |
|
|
Term
|
Definition
|
|
Term
|
Definition
| (“PS I + PS II”) oxygenic/aerobic best |
|
|
Term
|
Definition
| excitation of e- splitting them off from a donor at reaction center |
|
|
Term
| photolysis occurs in-- which is -- and contains-- |
|
Definition
| thylakoid membranes- special structures that harvest light. Contains ATP synthase |
|
|
Term
| photo auto trops do the -- rxn's in photosynthesis |
|
Definition
|
|
Term
| Dark rxn starts with -- and does the -- |
|
Definition
|
|
Term
Photo heterotrophs
light-
carbon-
calvin- |
|
Definition
light- still a source of energy
carbon comes from outside organic material outside the microbe (glucose/protein/lipids)
DONT FIX carbon= no CALVIN |

|
Term
| photolysis system characteristics |
|
Definition
4 SHARED- every system must have
1. antenna system
2. rxn center
3. Electron transport system
4. Energy carriers |
|
|
Term
|
Definition
| pigments (chlorophylls) absorb light |
|
|
Term
|
Definition
| where e- is removed from donor |
|
|
Term
| Energy carriers in photolysis |
|
Definition
|
|
Term
| Of the 3 photosystems what has to happen vs what makes them different? |
|
Definition
ATP has to be produced
Difference comes from whether you get reducing power- does it make NADPH or not? |
|
|
Term
|
Definition
Chloroflexus(green non sulfur bacterium),
Rhodospirillum rubrum(puple non sulfur bacterium) |
|
|
Term
| PS2 is -- phosphorylation meaning e- are - |
|
Definition
| Cyclic phosphorylation: electrons returned to donor |
|
|
Term
|
Definition
| : bacteriochlorophyll (e- ripped off run thru ETC and then returned to bacteriochlorophyl) |
|
|
Term
|
Definition
NO NADPH (reducing power)
NO e- transfer
ATP: photophosphorylation |
|
|
Term
| Why does PS2 not create NADPH? |
|
Definition
| bc it is cyclic. TO form NADPH it needs two e- and two H+ |
|
|
Term
|
Definition
| Chlorobium (green sulfur bacterium |
|
|
Term
| PS1 is -- phosphorylation meaning e- -- |
|
Definition
| Noncyclic phosphorylation: e- permenately removed from donor |
|
|
Term
|
Definition
| : H2S, Fe 2+, organic donor (microbe dependent) lithotrophs |
|
|
Term
|
Definition
NADPH (reducing power)
ATP: photosphorylation
ATP synthase not pictured |
|
|
Term
|
Definition
| Anabaena spiroides, Prochlorococcus marinus |
|
|
Term
| Because Z pathway is -- between PS1 and PS2 it makes it the -- |
|
Definition
|
|
Term
| Z pathway is -- phosphorylation |
|
Definition
| noncyclic phosphorylation |

Term
| energy carriers in Z pathway |
|
Definition
NADPH (reducing power)
ATP: photophosphorylation |
|
|
Term
| Z pathway rips e- off -- to form -- meaning they need -- |
|
Definition
water
molecular O2
need SOD and peroxidase to be around O2 =obligate aerobes |
