What thyroid hormone regulates general activities related to metabolism and oxidation?

The thyroid hormone primarily responsible for regulating general activities related to metabolism and oxidation is thyroxine, also known as T4. T4 is produced by the thyroid gland and plays a crucial role in increasing the metabolic rate, influencing how the body utilizes energy, and regulating various physiological processes. It is converted into the more active form, triiodothyronine (T3), which exerts stronger effects on metabolism and is essential for growth and development. Together, T4 and T3 maintain metabolic homeostasis in the body.
