Nutrient sensing pathways involved in autophagy include mTOR, AMPK, and acetyl-CoA protein deacetylation.

“so you have sort of the mTOR pathway which is mostly sensing amino acids you have the ampk pathway which is mostly sensing energy and ATP in general and then you have sort of the acetyl co a protein deacetylation pathway which is also just basically sensing substrate of fatty acid and glucose is that sort of a fair way to say that those are three ways that nutrient low nutrients can still trigger the same pathway”
