Explanation:
Hormones are chemical signals secreted by animals and plant that are capable of regulating body activities and maintain homeostasis.

When they bind with their receptors, the target cells will synthesize specific proteins that produce the characteristic effect of the hormone.
The main function of the smooth ER is to make hormones and lipids.
