The phrase "activity was attributable to" is correct and usable in written English.
It can be used to indicate that a specific activity is the result of or linked to a particular cause or factor.
Example: "The increase in sales activity was attributable to the new marketing strategy implemented last quarter."
Alternatives: "activity was due to" or "activity was linked to".
This increased photocatalytic activity was attributable to synergistic effects of facilitated electron transfer by PtNPs.
On the other hand, anti-glucosidase activity was attributable to total proanthocyanidin contents in both the leaf and rhizome extracts.
This activity was attributable to production of amicoumacin A, which has been reported previously to inhibit methicillin-resistant Staphylococcus aureus and Helicobacter pylori, and to display anti-inflammatory and antitumor effects.
In most cases the antibacterial activity was attributable to hydrogen peroxide produced by the bee-derived enzyme glucose oxidase.
To minimize the possibility of non-specific in vitro inhibition of parasite growth and to ensure that the inhibitory activity was attributable to the antibodies alone, we used IgG purified from each serum sample (Figure 4).
The difference in the total antioxidant activity was attributable to the hydrophilic phase.
Furthermore, we were unable to identify a new target for Hsp70 in the process of caspase-9 activation, indicating that its inhibitory activity is attributable to another indirect effect, instead of a direct one as previously reported.
Some 90% of companies' cloud activity is attributable to individual employees and small teams, rather than corporations' business-technology groups.
To determine whether differences in neural activity were attributable to changes in the cell composition of our long-term co-cultures, flow cytometry was used to assess the ratio between neurons and glia, in addition to characterizing the astrocytic phenotype (see section below).
To determine whether the increase in PK activity is attributable to PKM2 and responsible for impaired glycolysis caused by PARP14 knockdown, we co-expressed PKM2 shRNA (shPKM2) in PARP14-depleted cells (Fig. 4e) and determined the possibility of rescuing the metabolic effects observed in these cells.
The calculated threshold intensity between the first and 0.5th-order light-intensity dependences for FB-BWO was appreciably lower than that of ML-BWO, suggesting that the higher FB-BWO activity is attributable to the larger effective particle size for accumulation of two (or four) electrons.
