Detailed explanation-1: -Metabolism: thyroid hormone increases the basal metabolic rate. It increases the gene expression of Na+/K+ ATPase in different tissues leading to increased oxygen consumption, respiration rate, and body temperature.

Detailed explanation-2: -T3 and T4 increase the basal metabolic rate of almost all the cells in the body. High levels of iodothyronines lead to a slight increase in body temperature and a decrease in heat tolerance. Low levels of iodothyronines produce a decrease in basal metabolic rate and a decreased tolerance to the cold.

Detailed explanation-3: -Stimulation of the cells by T4 and T3 led to a dose dependent increase of oxygen consumption and glucose uptake, whereas T2 and rT3 had no effect. Thyroxine as well as T3 stimulated the cellular glucose metabolism, but lactate production was independent of T3 and T4 stimulation.

Detailed explanation-4: -The thyroid gland releases triiodothyronine (T3) and thyroxine (T4). These hormones play an important role in regulation of your weight, energy levels, internal temperature, skin, hair, nail growth, metabolism and is an important part of the endocrine system.

Detailed explanation-5: -T3 helps the body burn fat tissue and activate brown fat to further increase metabolism and increase fat burn (5). The addition of T3 helps to normalize these processes and can increase your body temperature to normal levels (and help increase your metabolism in the process).
