Question
Mention three essential properties of a hormone.
Answer
Three essential properties of a hormone are:
- Specificity: A hormone is specific in its action and affects only certain target cells or tissues.
- Sensitivity: The target cells or tissues of a hormone possess receptors that are highly sensitive to the hormone and respond to even small amounts of it.
- Regulation: The secretion of hormones is tightly regulated by feedback mechanisms involving the endocrine glands, the hypothalamus, and other organs.
