biol 227 Test Study Questions with
Complete Solutions
What's P680 - ANSWER reaction centre of chlorophyll a, associated with photosystem II
whats P680* - ANSWER after excitement of electrons
RuBisCO I - ANSWER primary from of photosynthetic species, OG is cyanobacteria
RuBisCO II - ANSWER bacterial enzymes and dinoflagellates
low select for CO2
RuBisCO IV - ANSWER does not have carboxylase or oxygenase activity. Important in sulphur
reactions
Photorespiration - ANSWER Oxygenase activity that occurs in efficient forms of RuBisCO
or when O concentrations are high compared to caron dioxide
Rubisco 1A and 1B - ANSWER not efficient at carboxylase over oxygenase activity
1A- Found in Cyanobacteria. Poor at Carboxylase activity. Thus, cyanobacteria have an
extreme effective suite of CCMS
1B- Plants, chlorophytes (green algae)
RuBisCO most efficient - ANSWER 1D
measuring photosynthetic rates - ANSWER •Oxygen evolution (most common)
