Yes, because adrenaline is a sugar-producing hormone, it can promote the increase of blood sugar, for example, through gluconeogenesis and proteolysis, so that blood sugar can be increased, and insulin secretion can be promoted in a feedback way, so that blood sugar can be decreased. The direct impact is that in order to raise blood sugar, insulin secretion must be reduced before blood sugar can drop. Look at this paper, and you will know: evolutionary insight regulates the mechanism of persistent release of norepinephrine and heterog protein. Straubots, Sharp GW.
