Thyroid hormones increase metabolism and increase body ______.

• A. temperature
• B. water retention
• C. fat storage
• D. weight

Answer: (A)

Verified step by step guidance

1. Understand the role of thyroid hormones: Thyroid hormones, such as thyroxine (T4) and triiodothyronine (T3), are responsible for regulating metabolism in the body. They influence how the body uses energy and produce heat as a byproduct of increased metabolic activity.
2. Analyze the options provided: The options include temperature, water retention, fat storage, and weight. Consider how each of these might be affected by an increase in metabolism.
3. Relate metabolism to body temperature: Increased metabolism leads to more energy being used by cells, which generates heat. This is a direct link between thyroid hormones and body temperature.
4. Eliminate unrelated options: Water retention, fat storage, and weight are not directly increased by thyroid hormones. In fact, increased metabolism often leads to fat breakdown and weight loss, not gain.
5. Conclude the correct answer: Based on the physiological role of thyroid hormones, the correct answer is 'temperature,' as increased metabolism directly raises body temperature.
