The phrase "activity which is involved" is correct and usable in written English.
It can be used when describing a specific action or task that is part of a larger process or situation.
Example: "The project requires an understanding of the activity which is involved in the data collection phase."
Alternatives: "task that is included" or "process that is engaged".
As the morning transitions to mid-day, functional enrichment becomes dominated by photosynthesis and related processes, such as photosystem I, photosystem II, and chloroplast thylakoid membrane, the glutamyl-tRNA reductase activity which is involved in heme porphyrin biosynthesis of chlorophyll [51].
Water-based extract from CZ was a potent inhibitor of VEGFR2 kinase (Vascular Endothelial Growth Factor Receptor) activity which is involved in angiogenesis [ 78].
The GGDEF domain exhibited diguanylate cyclase (DGC) activity, which is involved in the synthesis of cyclic-di-GMP from two GTPs.
Both of these proteins have intrinsic histone acetylase activity, which is involved in modifying chromatin structure in nucleosomes and thereby regulating gene expression [ 53].
CPT I activity, which is involved in fatty acid oxidation, was inhibited by a HF diet and stimulated after KO supplementation.
Furthermore, adipose tissue had downregulated genes involved in the extracellular matrix activity which is involved in multiple processes including modulation of immune responses.
The present study was designed to compare the effects of palm vitamin E which mainly contains tocotrienols and α-tocopherol supplementation on catecholamines and gastric xanthine oxidase activity, which are involved in stress-induced gastric lesions in rats.
These peptides are of particular interest because their oxidation may not just serve as an early warning of age-induced changes in the oxidative status of cells, but might induce changes in their activity, which are involved in controlling or triggering the oxidation of proteins in general.
On the same time, changes of Glu and GABA concentrations detected in vivo in basal ganglia of PD patients could be suggestive of dysfunction of neuronal excitatory and inhibitory activities which are involved in the control of movements.
