Verified step by step guidance

Understand that thyroxine, also known as T4, is a hormone produced by the thyroid gland.

Recognize that the primary role of thyroxine is to regulate the body's metabolism, which includes the rate at which the body uses energy.

Metabolism involves various biochemical processes that convert food into energy, which is essential for maintaining bodily functions even at rest.

Thyroxine influences the metabolic rate by increasing the basal metabolic rate (BMR), which affects how quickly cells use energy.

By regulating metabolism, thyroxine plays a crucial role in energy production, growth, and development, making it essential for overall health and well-being.
