All are functions of thyroid hormone except: Decreased Na+/K+ pump activity. Sets basal metabolic rate. Stimulates gluconeogenesis. Builds skeletal muscle proteins.

The function that is not associated with thyroid hormone is "Decreased Na+/K+ pump activity."

Here's why:

1. Sets basal metabolic rate: Thyroid hormones, specifically triiodothyronine (T3) and thyroxine (T4), play a crucial role in setting the basal metabolic rate, which is the rate at which your body uses energy when it is at rest. They do this by activating genes that increase the number of mitochondria in cells, thereby increasing the overall metabolic activity of the body.

2. Stimulates gluconeogenesis: Gluconeogenesis is the process of producing glucose from non-carbohydrate sources. Thyroid hormones stimulate this process to ensure that there is a steady supply of glucose for the body to use as energy.

3. Builds skeletal muscle proteins: Thyroid hormones also play a role in protein synthesis, including the proteins found in skeletal muscle. They do this by increasing the rate of protein synthesis and decreasing the rate of protein degradation.

4. Decreased Na+/K+ pump activity: This is not a function of thyroid hormones. The Na+/K+ pump is a crucial component of cell membranes, helping to maintain the electrochemical gradient that allows neurons to send signals. While thyroid hormones can affect many different systems in the body, they do not directly decrease the activity of the Na+/K+ pump.
