The insulin signaling pathway inhibits the synthesis of the Foxo transcription factor proteins that would otherwise increase cellular longevity. Downregulation of the insulin signaling pathway has several other functions, choose right one

#Unit 5. Developmental Biology

It appears to influence metabolism, increasing mitochondrial electron transport.
When the DAF-2 receptor is not active, cells increase the production of enzymes that prevent oxidative damage, as well as DNA repair enzymes.
This lack of insulin signaling increases fertility.
Decrease in DNA synthetic enzymes and in enzymes that protect against ROS is due to the Foxo/DAF-16 transcription factor
