Crassulacean Acid Metabolism (CAM) Plants - ✔✔mode of carbon fixation
in which CO2 is incorporated into a variety of organic acids at night within
the plant, to be used as part of the Calvin cycle during the day when ATP
and NADPH is made available
C4 Plants - ✔✔A plant that prefaces the Calvin cycle with reactions that
incorporate CO2 into four-carbon compounds, the end product of which
supplies CO2 for the Calvin cycle.
Photorespiration - ✔✔a process in which the enzyme rubisco reduces
carbon fixation in photosynthesis by binding with oxygen instead of with
carbon dioxide
C3 Plants - ✔✔A plant that uses the Calvin cycle for the initial steps that
incorporate CO2 into organic material, forming a three-carbon compound
as the first stable intermediate.
, 3 Phases of Calvin Cycle - ✔✔1. Carbon fixation
2. Reduction
3. Regeneration of the CO2 acceptor
Glyceraldehyde 3- Phosphate (G3P) - ✔✔the sugar produced from the
Calvin cycle
Cyclic Electron Flow - ✔✔uses only photosystem I and produces ATP, but
not NADPH; Ex: used by photosynthetic bacteria to produce its own energy
Linear Electron Flow - ✔✔the use of photosystem I and II to produce ATP
and NADPH for the Calvin Cycle
Photosystem II - ✔✔a light-harvesting complex that uses hydrogen ions the
splitting of water (by-product being oxygen) to pump through the
cytochrome complex (electron transport chain) that produces ATP
Photosystem I - ✔✔a reaction-center complex that generates NADPH
through the Fd (electron transport chain)
Primary Electron Acceptor - ✔✔in chloroplasts, an acceptor of electrons
lost from chlorophyll a; found in the thylakoid membrane
Reaction-Center Complex - ✔✔a complex organized into associated
proteins holding a pair of chlorophyll a molecules and primary electron
acceptor (PS I)
