Final answer:
The correct names for the hormones L-thyroxine (T4) and Triiodothyronine (T3) are Thyroxine and Triiodothyronine. The correct answer is option 2.
Step-by-step explanation:
Thyroxine and Triiodothyronine are, respectively, L-thyroxine (T4) and Triiodothyronine (T3). They control the basal metabolic rate of the organism and are produced by the thyroid gland. Target cells frequently undergo a conversion from the more potent T3, which has three iodine atoms, to the more prevalent T4, which has four iodine atoms. These hormones are essential for metabolism. The correspondingly named triiodothyronine and thyroxine affect organ function and energy levels. A larger abundance of T4 affects the generation of T3, which is essential for cellular function. Overall metabolic processes are impacted by their interaction, with T3 being more physiologically active and influencing vital body functions. Managing thyroid-related conditions and metabolic abnormalities is made easier with an understanding of their responsibilities.
