Description:
Activity of external carbonic anhydrase (eCA) using the depletion of 18O of aqueous 13C18O2 caused by hydration and dehydration steps of CO2 and bicarbonate. Shown as the ratio of catalyzed CO2/bicarbonate conversion rate compared to the uncatalyzed rate and normalised to chlorophyll. Units are Fold Activity compared to uncatalyzed rate; normalised to chlorophyll concentrations.
