PHOTOSYNTHESIS: CARBON METABOLISM Flashcards
pathway by which all photosynthetic eukaryotic organisms ultimately incorporate C02 into carbohydrate is known as carbon fixation
photosynthetic carbon reduction cycle
the PCR cycle is commonly referred
c3 cycle
3 stages in Calvin cycle
Carbon fixation
Reduction of 3-PGA
Regeneration of the Acceptor Molecule
this process involves the reoxidation of
products just previously assimilated in photosynthesis
photorespiration
the concentration of C02 at which uptake for photosynthesis is balanced by the evolution of C02 by respiration or other processes
CO2 compensation concentration
also known as the photosynthetic carbon oxidation (PCO) cycle
C2 glycolate cycle
Plants that incorporate carbon solely through the PCR or Calvin cycle are generally known as
C3 plants
In C4 leaves the vascular bundles are quite close together and each bundle
is surrounded by a tightly fitted layer of cells
bundle sheath
key to the C4 cycle
PEPase
inverse of transpiration ratio
water use efficiency
named because
it was originally studied most extensively in the family
Crassulaceae.
Crassulacean acid metabolism (CAM)
linear polymer of glucose created by linking adjacent glucose residues between the
first and fourth carbons
amylose
soluble disaccharide containing a glucose
and a fructose residue
sucrose
