Question

Acting alone, epinephrine and thyroid hormone each stimulates release of only a small amount of fatty acids from adipose cells. in the presence of thyroid hormone, epinephrine causes a much more substantial release of fatty acids from the cells. what is the term describing the effect of thyroid hormone on epinephrine's actions?

Answer 1

I agree thanks for helping :)

Answer 2

The effect of thyroid hormone on epinephrine's actions is a mechanism known as permissiveness.
Permissiveness is a relationship between hormones when the presence of one hormone is required in order to allow a second hormone to exert its full effects. Thyroid hormones have a possibility to increase the number of epinephrine receptors on the target cell.
