Chapter 8 Flashcards
The light defendant reaction occurs in ….the vali in cycle occurred in …..
Thylakoids
Stroma
What are the two light reactions that happen in thylakoids ?
Non-cyclic electron pathway
Cyclic electron pathway
The non cyclic electron pathway begins with photo system 2 or 1?
2
What’s the name of chlorophyll pair in which photons are concentrated?
Reaction center
Where do electrons go after scraping the reaction center?
Electron acceptor
Where does the energized electron go after leaving the electron acceptor ?
Electron transport chain
In which photo system NADPH is formed?
Photo system one
Under what condition photosynthetic cells enter cyclic electron pathway?
Under environmental condition, such as high oxygen levels, NADPH levels may accumulate in the cell
What’s the enzyme through which hydrogen ions move from thylakoids to stroma?
ATP synthase
What’s the method of ATP production in thylakoid is called?
Chemiosmosis because ATP production is tied to the an hydrogen ion gradient
What are three phases of Calvin cycle?
CO2 fixation
CO2 reduction
Generation of RuBP
What happens in the carbon fixation step of Calvin cycle?
3 CO2 from atmosphere are attached to three molecules of RuBP(5 carbon molecule)
The 3 six carbon molecules are unstable and break into 6, three carbon molecules called PGs(phosphoglycerate)
What’s the enzyme that speeds the CO2 fixation reaction in Calvin cycle?
RuBP carboxylase
How many times should Calvin cycle run to produce one glucose ?
6 times
What’s the product of the first step of Calvin cycle?
3-phosphoglycerate
or
3PG
