The phrase "activate feeding" is correct and usable in written English.
It can be used in contexts related to starting or enabling a process of feeding, often in technical or biological discussions.
Example: "To ensure the system operates efficiently, you must first activate feeding before proceeding with the next steps."
Alternatives: "initiate feeding" or "start feeding process".
Among five serotonin receptor null mutants, only ser-7 tm1325) ser-7 tm1325tivate failedg in response to serotonin.
However, we found that ADF could activate feeding as effectively in the absence of mod-5 as in its presence, suggesting that serotonin from ADF directly activates SER-7.
Among the tested mutants, only the ser-7 null mutant failed to activate feeding in presence of serotonin, confirming the previous report that serotonin activates feeding via a type 7 serotonin receptor SER-7 (Hobson et al., 2006; Song and Avery, 2012).
Serotonin suppressed feeding in the ser-7 null mutant, suggesting that serotonin suppresses as well as activates feeding.

Ghrelin stimulates appetite, mediates stress-activated feeding, promotes adiposity, and inhibits the effect of CCK on vagal afferent neurons (2, 36– 36).
Thank you for choosing to send your work entitled "Recognition of familiar food activates feeding via an endocrine serotonin signal in C. elegans" for consideration at eLife.
(H ) Serotonin signaling via SER-7 that activates the feeding response is more active on familiar food than novel food.
The released serotonin activates the feeding response mainly by acting humorally and directly activates SER-7, a type 7 serotonin receptor, in MC motor neurons in the feeding organ.
In conclusion, only familiar bacteria activate ADFs, which increases serotonin release from the neurons and subsequently activates the feeding response.
Thus, we propose that a social affordance is activated when feeding a conspecific.
