Question
Glycolate accumulates in chloroplast there is
low CO2
high CO2
bright light
low temperature
Solution
A.
low CO2
Glycolate is a respiratory substrate in photo respiration, which is formed in high concent ration of O2 but low concentration of CO2 under the influence of RuBP oxygenase in chloroplast. When temperature and CO2 content are high the affinity of RuBP carboxylase increases for O2 but decreases for carbondioxids. Glycolate is produced as intermediate in C3 cycle.
