Question

Quizplus · Accepted Answer

Thyroid hormone interacts with its target tissue by binding to receptor molecules in the nucleus, which then activate genes that promote various cellular functions such as metabolism and growth. This is known as genomic action, and it is the primary mechanism by which thyroid hormone acts on cells. The other options listed do not accurately describe how thyroid hormone interacts with its target tissue.
