What is the primary function of hormones? 1) act as chemical messengers that regulate the metabolic function of cells in the body 2) influence metabolic activity of glands by electrochemical impulses 3) activate extracellular enzymes function as enzymes that catalyze the breakdown food molecules

1) act as chemical messengers that regulate the metabolic function of cells in the body

Explanation:

Hormones are produced by endocrine glands and released into the blood stream, where they travel until they reach their target tissues. Once there, they produce a particular biological or physiological effect in the target cells. Because of this, they act as chemical messengers between different cells in our bodies.

An example of a hormone is insulin. When blood sugar levels are high, the pancreas releases insulin, which promotes glucose uptake by the cells in the body, thus decreasing the blood sugar levels and taking them back to normal.
