If a patient with a thyroid tumor begins overproducing T4, which consequence affecting peripheral tissue is most likely?

💡 Explanation

Increased thyroid hormone levels from the tumor will cause upregulation of thyroid hormone receptors (TRα1) in peripheral tissues because of genomic regulation; therefore, receptor expression increases, rather than decreased ATP production or altered glycogen metabolism, which are longer-term adaptations, not direct gene expression changes.
