The phrase "activity when it is" is not complete and lacks clarity in written English.
It could be used in contexts discussing the timing or conditions of an activity, but it needs additional information to convey a clear meaning.
Example: "The success of the project depends on the activity when it is at its peak."
Alternatives: "task during its" or "action at the time it is".
For instance, the prototype BVMO, cyclohexanone monooxygenase, loses dramatically its activity when it is incubated with 5% of solvents and its tolerance is very poor, since after 20 min incubation with 5% methanol the enzyme is completely inactivated (Secundo 2011).
We present, in Section The binding of 5mTHF to GNMT, evidence from the mathematical modeling that GNMT retains 50%% of its activity when it is once bound by 5mTHF but not when it is twice bound.
Is it possible that ICT1 needs to maintain this activity when it is assembled into the mitoribosome, in vivo?
The incorporation of gC3N4 leads to a further improvement on the photocatalytic activity when it is specifically done over TiO2.
It is known that the short-latency stretch reflex (SLSR) is modulated by the background muscle activity when it is elicited at matched torque levels.
Sudden alterations to millions of contracts can have large effects on economic activity, so faster inflation can stimulate real activity when it is unexpected.
To ensure that the recombinant enzyme expressed and purified in our experimental settings was fully active, we determined its specific activity when it was freshly prepared as well as prior to performing the thermodynamic experiments.
Because the plasmin completely lost its activity when it was incubated with Zn2+ and Cu2+ [ 32, 33].
Deferoxamine (40, 80 or 157 mg/kg, three times a day) did ameliorate disease activity when it was administered during active disease in male SJL mice given purified MBP and pertussis toxin injections (Pedchenko and LeVine, 1998; Table 1).
Whether the star's activity when it was younger could have stripped Proxima b of an atmosphere remains to be discovered, while it is also unknown if the planet has a magnetic field which could potentially protect it from such radiation.
