Question

Thyroid hormone is required for the production of beta adrenergic receptors in the smooth muscle of the bronchioles. Once the beta adrenergic receptors are produced, epinephrine can bind to these receptors, inducing dilation of these tubules. This hormone interaction can be described as __________.

Answer 1

Answer: This hormone interaction can be described as SIGNAL TRANSDUCTION.

Explanation: Transduction refers to the binding of specific signaling molecule (such as hormone) to a specific receptor to bring about specific response. The binding of the signaling molecules changes the receptor protein in some way, initiating the process of Transduction.

The transduction stage converts the signal to a form that can bring about a specific cellular response. Transduction may occur as a single step; but is often a sequence of changes with series of molecules (The signal transduction pathway). The molecules in the pathway are called RELAY MOLECULES.
