Question

Define hormone? Mention the characteristics of hormones.

Answer 1

Hormones are special chemicals that are released in the body that controls and regulate the activity of certain cells and organs. These hormones are secreted by the Endocrine glands.

They function in the regulation of physiological activities and in maintaining homeostasis in the body.

They are transported to the target cells/ tissue/organ via blood circulation. Their actions are species specific and mostly water soluble. They are low in molecular weight and chemically heterogeneous sub­stances.
