Concept explainers
To define:
The term hormone.
Introduction:
The “hormone” is a chemical molecule that is used to transfer information inside the cell. These chemical messengers are released from the endocrine cells in the body. The hormone molecules bind to the specific receptor molecules present on the membrane of the cell.
Explanation of Solution
The hormone is a chemical messenger molecule present inside the cell. It is secreted from the endocrine cells in the body. Each hormone binds to a specific receptor present on the membrane. The cell signaling is activated after binding of ligand hormone on the receptor. There is a change in the structure and conformation of the hormone receptor after binding by the hormone. It activates the protein kinases in signaling cascade pathway. The
