The phrase "active uptake" is correct and usable in written English.
It can be used in contexts related to biology, nutrition, or any field discussing the process of absorbing or taking in substances actively.
Example: "The study focused on the active uptake of nutrients by plant roots, highlighting the importance of soil composition."
Alternatives: "dynamic absorption" or "energetic intake".
The term metabolic imaging is pertinent to radiotracers that have active uptake into tumours based on basal metabolic rates or increased proliferative activity.
Choline is obtained by the active uptake of extracellular choline, a breakdown product of previously released acetylcholine.
Under such conditions, water movement is caused by active uptake of ions (charged particles) and by the entry of water from the soil into the roots.
Both drugs show active uptake at the blood brain barrier (BBB).
In vitro studies have demonstrated the active uptake of HB GO into the cytosol of tumor cells.
The tolerance to ~1 kGy of gamma radiation exhibited by KMSZP6 cells is of relevance to active uptake of Cs and Sr from radioactive nuclear waste.
In contrast, it showed insignificant binding to B16F1 cells at 0 °C; perhaps indicating the involvement of an active uptake pathway towards its binding to melanoma cells.
This may counteract the lower active uptake and the faster elimination from the blood stream of small NPs (Albanese et al. 2012; Perrault et al. 2009).
The accumulation of heavy metals in algae includes two different methods, an initial rapid (passive) uptake followed by a much slow (active) uptake (Cho et al. 1994).
There are two major ways of the NPs uptake into the cell: active uptake by endocytosis and passive uptake by diffusion.
Both passive biosorption and active uptake of pollutants by cyanobacterial cell are termed "Bioaccumulation", and the phenomenon is referred to as phycoremediation tool (Malik 2004; Sharma 2012).
